00 /SERVICE · MIGRATE
Base44Devs is a fixed-price Base44 migration service, from $6,000, for teams that need to migrate from Base44 to a stack they control. Default target: Next.js + Supabase on Vercel. Zero data loss, full code ownership, written cutover plan with a rollback path. Typical downtime under five minutes.
Short answer
Last reviewed · 2026-09-23
Migrating off base44 with Base44Devs involves three deliverables: a data export and schema map, a code rewrite on the target stack, and a DNS-cutover plan with a tested rollback path. The default target is Next.js + Supabase on Vercel. Fixed-price migrations start at $6,000for apps with up to 5 tables and 10 routes (Small), $12,000 for up to 20 tables with multi-role auth and Stripe (Medium), and $25,000+ for multi-tenant or SOC 2 / HIPAA-compatible builds (Enterprise). Typical production downtime at cutover is under five minutes; the base44 workspace stays live as rollback for a 14-day stability window after switch. A hired rewrite is only one of four routes off the platform — an automated migrator replicates the app onto your own infrastructure without converting the stack, base44’s own export supports a do-it-yourself rebuild, and an open-source drop-in SDK shim points the exported frontend at Supabase. Pick the route before the destination.
01 /WHEN TO MIGRATE
Migration is not the right call for every base44 app. If none of the triggers below applies, staying on the platform is usually the cheaper move. Our Base44 review weighs the pros and cons, including where the platform still earns its keep. We will tell you that on the scoping call. When the stay-or-migrate decision needs a written answer for a board, a Base44 consulting call scopes the written recommendation that provides it. The same test written out in full is when it is actually time to leave Base44.
TRIGGER 01
The migration ROI calculator takes your all-in monthly base44 spend (subscription, the plan upgrade you buy when credits run out, integration fees and engineer time on platform work) and your app's size, sets it against an estimated Vercel + Supabase run cost for an app that size, and divides the one-time migration fee by the difference to give a payback window.

TRIGGER 02
Base44 states its platform holds SOC 2 Type II and ISO 27001 certification and is independently penetration-tested, with the SOC 2 report and a GDPR DPA available on request (base44.com/security, read 23 Sep 2026). That covers Base44's own controls; it does not attest your app's configuration — row-level security, secrets, auth rules — which a security questionnaire will still ask about. App data is stored in the US by default and only Elite and Enterprise workspaces can choose another region, and Base44's terms bar protected health information and payment-card data from the platform unless expressly agreed in writing in advance.
TRIGGER 03
Base44's terms of service provide the platform "as is" and "as available" and do not guarantee it will be uninterrupted. Its security page says detailed commitments are available to Enterprise customers as part of their Service Level Agreement. Below Enterprise, a customer who needs a contractual uptime guarantee either accepts platform risk or migrates.
TRIGGER 04
The AI agent's context resets across sessions and rewrites components on long runs. Past a certain product complexity the agent costs more time than it saves.
TRIGGER 05
The Wix acquisition (announced 2025) introduced platform-strategy uncertainty. If your business cannot tolerate roadmap or pricing changes outside your control, migration de-risks the dependency. Our State of Base44 2026 report tracks post-acquisition shipping cadence and the most-upvoted open feature requests. Read more →
02 /HOW YOU LEAVE
An automated migration tool is the right call when you want the same app on accounts you own and a base44-shaped backend is fine; it beats a hired rewrite on price and calendar. A done-for-you migration service earns its price when the architecture is why you are leaving: server-rendered pages, SQL, or a permission model an auditor must sign off.
There are four ways off base44, and three of them are not us. Before you pick a destination, pick a route. The route decides what the move costs, how long it takes, and — the part most people find out too late — whether you actually leave base44’s architecture or just move a copy of it onto your own bill.
| Route | What actually happens | Where you land | What it costs you | When it is the right call |
|---|---|---|---|---|
| Automated replica | What actually happensA migrator logs into your base44 account and pulls the whole app — including the backend the code export leaves behind — then redeploys it onto accounts you own. Nothing is rewritten. | Where you landYour original React frontend on a base44-shaped backend. The one we checked publishes its target stack as Python/FastAPI plus MongoDB, on your own hosting and MongoDB Atlas, with the code in your GitHub. | What it costs youA one-time price per app, shown after you log in; the migrator we checked publishes no price list. Any hosting and database charges land on your own provider accounts. | When it is the right callYou want the same app off the platform quickly, and a base44-shaped runtime is fine. The migrator we checked runs on any base44 plan, free tier included. |
| DIY rewrite | What actually happensYou take base44's own ZIP or GitHub export — gated to the Builder plan or higher — and replace every SDK call, backend function and auth path yourself. | Where you landWhatever you build. The export installs and renders, then fails on the first data call, because the SDK only authenticates against the platform. | What it costs youA Builder plan or higher for the export, then 80-200 engineer-hours of your own team's time. | When it is the right callYou have an engineer with the calendar for it. Our export guide puts the rebuild at 80-200 focused hours. |
| Drop-in SDK shim | What actually happensYou keep the exported frontend and swap base44's client for an open-source replacement that answers the same entity and auth calls from a Supabase project you own. You still create the Postgres tables yourself and move the data across. | Where you landYour React frontend, largely unchanged, on Supabase and Postgres. The integrations and any backend-function logic are yours to write. | What it costs youFree, MIT-licensed code, plus the engineer-hours to finish its placeholder integrations and move the data. | When it is the right callYour app is mostly entity reads and writes and you have an engineer to own the result. The open-source package we checked (github.com/Ai-Automators/base44-to-supabase-sdk, MIT, 167 stars) was last updated in August 2025. That is before base44's 27 November 2025 data-request cap. Its email, upload, LLM and image integrations are placeholders, so budget an engineer to finish and maintain it. (Checked 23 September 2026.) |
| Hired rewrite | What actually happensSchema export and integrity map, a parallel build on the target stack, an acceptance pack, then a DNS cutover with a tested rollback path. The four phases below. | Where you landAny of the eight destinations in the matrix below, chosen on fit rather than on what a tool supports. | What it costs youFixed price: $6,000 Small (2-3 weeks), $12,000 Medium (4-5 weeks), $25,000+ Enterprise. Includes a 14-day rollback window and a 30-day defects warranty. | When it is the right callThe architecture is the reason you are leaving — server-side rendering, SQL and relational integrity, or a permission model an auditor will sign off. |
A one-click migrator will beat us on price and on calendar, and for a large share of base44 apps that is the correct answer. If what you want is your app, working exactly as it does now, on infrastructure billed to you instead of rented from a platform, an automated replica gets you there in an afternoon and we will say so on the call. We would rather lose that engagement than sell a twelve-thousand-dollar rewrite to someone who needed a copy-and-redeploy.
Know what the replica is, though. It is faithful by design — it does not convert your stack, and the vendors say so plainly: base44 stores data in MongoDB and runs Python on the backend, so a replica lands on MongoDB and Python too. You finish owning a base44-shaped application: no server-side rendering, no SQL, no relational constraints, and a backend that reimplements the platform’s own. If your reason for leaving was cost, vendor risk, or wanting the code in your GitHub, none of that matters and the replica is a good trade. If your reason for leaving was the architecture itself — pages that must be server-rendered for every visitor, an auditor cannot sign off a permission model you cannot query, your team writes SQL — then a faithful copy preserves the exact thing you were trying to get away from. Search on its own is rarely that reason: Base44 already serves search engines and AI crawlers a prerendered copy of each page, so an app that is not showing in Google should be checked for a settings problem first — the SEO toggle off, pages set to noindex or behind a login — before the architecture is blamed.
Two practical notes on the automated route, both taken from the one migrator we read end to end rather than from the category as a whole. First, it runs on any base44 plan, free tier included, because it reads through your normal login rather than through the export — base44’s own ZIP and GitHub export is gated to the Builder plan or higher, which is what the code-export guide covers. Second, passwords do not leave base44. A replica forwards each user’s first login back through the platform once to capture it, which means you cannot delete the base44 app on cutover day — you keep it alive until your users have each signed in. Budget for that overlap month.
On every route the base44 subscription is the last thing you switch off. Base44’s billing docs say cancelling stops future renewals but “does not issue a refund for the current subscription period,” and at the end of that period the workspace drops to the free plan: apps stay live, but the plan caps you at five apps and you may lose features that are only available on paid plans. Time it to your renewal date; the steps and the refund terms are in how to cancel a Base44 subscription.
A rewrite is worth its cost in one situation: the platform’s architecture, not the platform’s bill, is what is stopping you. That is a smaller set of teams than the internet implies, and it is the only set we quote. The test is written out in full in the when-to-leave-base44 decision framework, and if you are not sure which side of it you are on, the $497 audit answers it in writing before you commit to anything — including the answer “use a migrator, you do not need us.” Teams whose problem turns out to be a handful of specific defects rather than the platform are better served by a fix sprint than by any migration at all.
03 /PRICING
Three sizing tiers based on table count and complexity. Every tier moves your data, users and uploaded files with zero data loss, keeps the base44 app live for a 14-day rollback window after cutover, and carries a 30-day defects warranty on the migrated code. Anything past Enterprise is quoted custom after a scoping call.

05 /TARGET STACK
The default target is not arbitrary. It solves the two biggest base44 limitations directly while introducing no new vendor lock-in.
We default to Next.js + Supabase because it solves the two biggest base44 limitations directly: Next.jsrenders every page on the server for every visitor, where base44 renders in the browser and hands a prerendered copy only to search engines and AI crawlers — so real users get finished HTML on the first response, and each page’s title, meta description and structured data live in code instead of a dashboard setting. Supabaseprovides Postgres-backed Row-Level Security that mirrors base44’s permission model with full portability — including the ability to self-host the database later. The combination is deployable to Vercel in one command, open-source at every layer, and introduces no new vendor-specific lock-in beyond standard Postgres + Node. If the real question is building directly on Supabase instead of on Base44, Base44 vs Supabase is the side-by-side.
Alternative targets we ship to: self-hosted Postgres + Node (when SOC 2 demands self-hosting), Firebase (when teams want a managed BaaS without Postgres), and other no-code platforms like Bubble, Lovable, Bolt, or Replit if a no-code-to-no-code move makes sense for your team.
Every destination has its own written playbook, because the work is genuinely different depending on where you land. The default path is documented step by step in migrate Base44 to Next.js and Supabase, and it starts the same way every other path does — you export your Base44 codebase first, then decide what it gets rebuilt on. If the driver is compliance rather than cost, the guide to self-host a Base44 app on Docker and Postgres covers the version where you own the machines; if the driver is only hosting, you can deploy a Base44 export to Vercel without changing the data layer at all, or move Base44 data to Firebase when the team wants a managed BaaS and no Postgres.
Teams that do not want to own code at all usually stay in no-code and pick a different builder. The three we ship to most often are documented the same way: move a Base44 app to Lovable when the app is UI-heavy and the AI workflow is the reason you came, rebuild a Base44 app in Bubble when the logic is workflow-shaped rather than code-shaped, and take a Base44 app to Replit when you want a real dev environment without standing up your own infrastructure. If you want code ownership from the first commit instead, the path to move from Base44 to Bolt.new keeps the AI-native workflow while handing you a normal project you can deploy anywhere.
Two things come before the destination choice, and both have their own written page:
base44 ejectis an exit: eject creates a new Base44 backend project with its own app ID and an empty database, and in Base44’s words “Your original app remains in Base44 unchanged.” If what you actually want is to keep the app on Base44 and work on it from your own editor, the Base44 vs Claude Code comparison covers that hybrid setup as well as the exit.| Destination | Best for | What you rebuild | Timeline | Rebuild effort |
|---|---|---|---|---|
| Next.js + Supabase | Best forThe default. Teams that want code ownership, server-side rendering, and a Postgres permission model that mirrors base44's. | What you rebuildEvery SDK call behind an abstraction layer, base44 RLS rules translated to Supabase policies, backend functions ported to API routes or Edge Functions. | Timeline4-14 weeks (median 6.5) | Rebuild effortHard · ~360 h |
| Vercel (Next.js + chosen backend) | Best forTeams whose blocker is hosting, SSR, edge, and CI — and who will pick the database separately. | What you rebuildThe exported React code ported into a Next.js project, SDK calls replaced against whichever backend you choose. Vercel does not choose the database for you. | Timeline4-10 weeks | Rebuild effortModerate · ~240 h |
| Self-hosted (Docker + Postgres) | Best forRegulated industries, data-residency requirements, and teams already operating infrastructure. | What you rebuildYour own Postgres, Node or Deno API, object storage, and auth — plus the operational surface: backups, monitoring, on-call. | Timeline10-16 weeks | Rebuild effortHard · ~480 h |
| Firebase | Best forTeams that want Google's managed serverless stack and do not need Postgres. | What you rebuildThe relational schema converted into Firestore documents — the significant piece — plus Cloud Functions for backend logic. Auth migration is smoother than most platforms. | Timeline6-10 weeks | Rebuild effortHard · ~280 h |
| Lovable | Best forUI-heavy apps whose owners came for the AI workflow and want to keep it, with real GitHub sync and a usable code export. | What you rebuildThe app rebuilt inside Lovable's editor, pointed at Supabase as the backend. Mostly mechanical. | Timeline3-5 weeks | Rebuild effortModerate · ~140 h |
| Bolt.new | Best forKeeping a fast prompt-to-deploy loop while ending up with a normal project you can host anywhere. | What you rebuildThe app rebuilt in bolt's WebContainers, then published on the website hosting and databases bolt's plans now include, or taken out as a normal project to host anywhere. | Timeline3-5 weeks | Rebuild effortModerate · ~140 h |
| Replit | Best forTeams that want a real development environment — shell access, real servers, real logs — without standing up infrastructure. | What you rebuildFrontend ports easily. Database, auth, and every base44 SDK call need replacing with Replit Database, Replit Auth, or external services. | Timeline3-6 weeks | Rebuild effortModerate · ~160 h |
| Bubble | Best forTeams leaving code behind entirely, or handing the app to a non-technical operator. | What you rebuildEvery page, in Bubble's visual editor. The data-model concepts map closely. Bubble's AI can draft an app from a prompt and its AI Agent (beta) adds features, but what it drafts is a new Bubble app, so each page is still rebuilt against your original. | Timeline6-10 weeks | Rebuild effortModerate · ~280 h |
The destination does not set the price. Our fixed-price tiers are sized by table count and complexity — Small $6,000 (≤5 tables, ≤10 routes), Medium $12,000 (≤20 tables, multi-role auth, Stripe), Enterprise $25,000+ (multi-tenant, SOC 2 / HIPAA-compatible) — so a twenty-table app costs the same to move to Firebase as to Supabase. What the destination changes is the calendar and the engineer-hours in the table above, and what you own once the cutover is done. If you want the payback arithmetic before you pick, the migration payback calculator takes two inputs, your current monthly base44 spend and your app’s size, and returns the payback window, the monthly saving and your net position after twelve months, using these fixed tiers and an estimated Vercel + Supabase run cost.
06 /CUTOVER
Four phases. The base44 app stays live until the new stack passes acceptance, so production users feel nothing during the build.
01/PHASE
All base44 tables are exported to portable SQL. Referential integrity is verified before any rebuild work starts. Foreign-key constraints, enums, and default values are preserved.
02/PHASE
The replacement stack is built alongside the live base44 app with no disruption to production users. Auth, RLS, payment integrations, and routes are reimplemented against the original spec.
03/PHASE
A test pack covering all critical workflows is run against the new stack before cutover. Pass criteria: 100% functional parity on the canonical user journey, no data divergence on the seeded record set, p95 latency at or below the base44 baseline.
04/PHASE
DNS is switched with the base44 app kept live as rollback. Typical production downtime is under 5 minutes. The base44 workspace is not deleted until a 14-day stability window passes.

08 /FAQ
Pick the route before the destination. A rewrite runs five steps: export the code (Base44's ZIP or GitHub export needs the Builder plan or higher), pull the records out one table at a time, copy uploaded files out of Base44 storage, replace every @base44/sdk call with the new backend, then switch DNS while the Base44 app stays live as the rollback. An automated migrator skips the SDK rewrite by standing up a Base44-compatible backend on accounts you own. Doing the rewrite yourself runs 80-200 engineer-hours by our export guide's sizing; our fixed-price migration service starts at $6,000.
When monthly credit cost exceeds the amortised cost of a custom stack, when you need an uptime commitment that Base44 reserves for Enterprise customers, when every visitor needs server-rendered pages rather than a client-rendered app, when the AI agent's context-window limits are slowing feature development, or when vendor-risk concerns following the Wix acquisition put the business at risk. Search visibility on its own is rarely the reason any more: Base44 apps render client-side for visitors, but Base44 serves search engines and AI crawlers a prerendered version of each page, refreshed when you publish (docs.base44.com, read 23 Sep 2026). The /audit engagement includes a migration cost projection if you want a quantitative answer before committing.
We design every cutover with a tested rollback path. The default plan keeps the base44 app live until DNS is switched and the new stack passes acceptance — typical production downtime is under 5 minutes. The base44 workspace is not deleted until the new stack passes a 14-day stability window, so rollback remains possible even after cutover.
Zero data loss is part of every fixed-price migration: every table moves with referential integrity preserved and paged past Base44's 5,000-items-per-request cap, uploaded files are copied out of Base44 storage, and the Base44 app stays live until the new stack passes acceptance. After cutover you have a 14-day rollback window and a 30-day defects warranty on the migrated code. Users keep their accounts but not their passwords: Base44 does not export password hashes, so on a rewrite each user sets a new password on first login. An automated replica avoids that reset by forwarding each user's first login through Base44 once, so the Base44 app has to stay alive until everyone has signed in.
Both. Data migration is a first-class deliverable: we export, transform, and load with referential integrity preserved. Auth user records, Stripe customer + subscription records, all application records, and webhook integrations are migrated. We never ask you to rebuild data manually.
Default target is Next.js + Supabase on Vercel. We also migrate to self-hosted (Postgres + Node), to Firebase, or to other no-code platforms (Bubble, Lovable, Bolt, Replit) — see the comparison pages for trade-offs. We pick the target stack that matches your team's skills, compliance requirements, and budget envelope.
Visually yes by default — we match the existing UX 1:1 unless you ask for a redesign. We do clean up obvious base44 quirks (client-side rendering for visitors, default styles, AI-generated layout drift). On the default Next.js target every page is rendered on the server for every visitor, not only for the crawlers Base44 prerenders for, so the first response already carries the finished page.
Yes, partly. Base44's ZIP download and GitHub connection both require the Builder plan or higher, and they give you the React frontend, your backend function source and a schema file. They do not give you a running app: the code imports @base44/sdk on every data call, and the SDK only authenticates against the platform. Your records come out separately, one CSV per table from the Data dashboard; a script that pulls them through the API instead has to paginate, because Base44 has limited data requests to 5,000 items each since 27 November 2025. Uploaded files and user password hashes are not in the export either: files have to be copied out of Base44 storage on their own, and password hashes never leave the platform, so on a rewrite every user sets a new password on first login to the new stack. AI-agent prompt history, the internal credit ledger and Base44's native analytics stay behind too; we replace the analytics with Plausible, PostHog or GA4.
Not the backend. In production, Base44 runs your database, auth and backend functions as a managed service. Its CLI's local dev server keeps data in an in-memory database that is cleared when the server stops, so it is a test bench, not a host (docs.base44.com, read 23 Sep 2026). You can host the frontend elsewhere: Base44's docs say its hosting 'currently supports Single Page Applications (SPAs) only' and that you can keep using its backend services while deploying your frontend to an external hosting provider. That moves the pages, not the dependency. Self-hosting the whole app means replacing that backend with one you run. An automated replica reimplements Base44's own backend shape on your accounts (the route matrix above); a rewrite onto your own Postgres, API, object storage and auth is our self-hosted destination: 10-16 weeks and about 480 engineer-hours in the matrix above.
Yes. Base44's backend service is managed: a MongoDB-compatible NoSQL database with row-level and field-level security, built-in authentication (email and password, social logins, SSO), Deno-based serverless backend functions on the Builder plan and above, and realtime subscriptions to record changes (docs.base44.com, read 23 Sep 2026). That backend is exactly what the code export leaves behind, which is why leaving means rebuilding it rather than copying it.
No. The CLI's eject command downloads your frontend code and backend resources and creates a new Base44 backend project with its own app ID. Base44's docs are explicit: 'The ejected project has an empty database. Your entity schemas are copied, but not your data.' and 'Your original app remains in Base44 unchanged.' Eject gives you the code in your own editor, still running on Base44. Leaving the platform still means replacing the @base44/sdk calls and the backend: the 80-200 engineer-hour job our export guide sizes.
Often, yes — and if that is the right answer for your app we will say so on the call. Automated migrators log in to your base44 account, pull the app including the backend the code export leaves behind, and redeploy it onto hosting and a database you own; the one we read in full runs on any base44 plan, free tier included. What they do not do is convert your stack. They replicate base44 faithfully, so you land on the same MongoDB-and-Python backend shape you started from, still without server-side rendering and still without SQL. Take the automated route when your reason for leaving is cost, vendor risk, or wanting the code in your own GitHub. Pay for a rewrite only when the architecture itself is the blocker — server-side rendering for every visitor, relational integrity, or a permission model an auditor will sign off. One caveat on either route: passwords cannot leave base44, so a replica forwards each user's first login back through the platform once, which means you keep the base44 app alive until your users have each signed in.
Fixed-price tiers based on table count and complexity: Small ($6,000, up to 5 tables and 10 routes, 2-3 weeks), Medium ($12,000, up to 20 tables, multi-role auth, Stripe, 4-5 weeks), Enterprise ($25,000+, multi-tenant architecture, SOC 2 / HIPAA-compatible, custom integrations). Every tier includes your data, users and uploaded files, a 14-day rollback window after cutover and a 30-day defects warranty on the migrated code. We quote custom for anything beyond Enterprise after a scoping call.
It stays active until cutover. We bill for the new stack to come online in parallel, then switch DNS once acceptance passes. After the 14-day stability window post-cutover, you cancel your base44 subscription. Cancelling stops renewals without refunding the current period, and at the end of that period the workspace drops to the free plan: a maximum of five apps, and the apps themselves stay live, though you may lose access to features that are only available on paid plans (docs.base44.com, read 23 Sep 2026). Nothing is archived for you, so decide what happens to the old app rather than assuming it goes dark. We do not require base44 to be deleted as a condition of any rollback.
