Base44 developer help · React, Vite, the Base44 back end
Fix your Base44 app.
It works in the editor, then payments, sign-in or data misbehave once published, or you have outgrown what the platform does. A senior engineer finds the cause, fixes it, and tells you plainly what leaving would involve.
Photography is illustrative.
- Front end
- React with Vite
- Back end
- Base44's own: entities for data, sign-in, backend functions in TypeScript, integrations
- Hosting
- Base44, at a base44.app address; custom domains from the Starter plan
- Code
- ZIP export; two-way GitHub sync from the Builder plan; the app uses @base44/sdk
Who this is for
For founders whose Base44 app works in the editor and needs to hold up for real users.
Base44 is about as all-in-one as app builders get: the front end, the data, sign-in, backend functions and hosting all come from the platform. The front end is a standard React app built with Vite. The back end is Base44's own service, which the app reaches through Base44's SDK, with data models defined as entities and server code in backend functions.
That shapes the work. Most fixes happen inside the platform and keep the app on Base44. Where a founder needs to leave, the front end moves easily and the back end does not, and an honest answer about that is part of what we give you.
Failure modes
The ways Base44 apps break.
These are what we look for first in a Base44 app, several taken from Base44's own documentation. None of them needs a rewrite.
-
Data rules wider than they should be
- What you see
- Base44's security scan flags a row-level security finding, or a user sees records that are not theirs.
- What is actually wrong
- Who can read and change each entity's records is set by rules. A rule loosened to make a feature work often stays loose.
- How we fix it
- Each rule written against who should see the record, then proven by signing in as one test user and trying to read and change another's data.
-
Payments that only work in the published app
- What you see
- Checkout does nothing in the editor, or customers land on a blank page after paying.
- What is actually wrong
- Base44's Stripe checkout runs only on the published app, not in the editor preview. Blank pages after payment often come from success and cancel URLs that do not point at the published domain. A Stripe sandbox has to be claimed within 60 days.
- How we fix it
- Return URLs set for the real domain, the Stripe account claimed and in your name, and the purchase, renewal and cancellation flow tested on the published app.
-
Custom-domain redirects that break sign-in
- What you see
- After adding a custom domain and redirect rules, logging in or resetting a password fails.
- What is actually wrong
- Base44 serves the login and password-reset paths itself, so redirect rules have to leave them alone.
- How we fix it
- Redirect rules rewritten to exclude those paths, and every sign-in route tested on the real domain.
-
Edits from GitHub that touch live data
- What you see
- A developer working locally changed real customer records, or merged changes that never appear in the app.
- What is actually wrong
- Base44's documentation says that in remote mode, writes go to the live app's production data. Synced changes do not go live until you click Publish. The branch must be named
main, and version history cannot go back to before GitHub was connected. - How we fix it
- A working agreement for who edits where, a test data set for local work, and publishing as a deliberate, checked step.
-
A back end you cannot take with you
- What you see
- You need something the platform does not do, or an investor asks what happens if you leave.
- What is actually wrong
- The app depends on
@base44/sdk. The front end can be hosted elsewhere while still using the Base44 back end, but self-hosting the back end is not documented. "Eject" creates a new, empty Base44 back end, copying the entity schemas but not the data. - How we fix it
- An exit plan sized before anyone commits: data exported, entities rebuilt on a standard database such as Postgres, SDK calls moved behind one interface, and the move made in steps so the app keeps running.
-
Secrets in the front end
- What you see
- An API key appears in the browser's network tab or the page source.
- What is actually wrong
- Backend functions read secrets on the server, and elevated access works only inside Base44-hosted functions. A key written into the React code is visible to every visitor.
- How we fix it
- Rotate the key, move the call into a backend function that reads the secret on the server, and check the built bundle.
Before you hire anyone
What to try yourself first in Base44.
- Revert in version history. Restore an older version, or publish one directly while you keep working on your draft.
- Discuss before it edits. Discuss mode makes no code changes until you approve them. For errors in the preview, Resolve with AI is free.
- Run the security scan. It checks row-level security, hardcoded secrets, backend functions, npm dependencies and the code itself. Fix every finding before real users arrive.
- Test payments on the published app. Checkout does not run in the editor preview. Test on the published app, and check the success and cancel URLs point at your real domain.
- Connect GitHub early. On the Builder plan or above, connect a repository whose branch is named
main. History from before the connection cannot be recovered later. - Back up the data. Use Data Backup and Restore if your plan includes it, and export what you can, so a bad change is recoverable.
How we work
How we work on a Base44 app.
With the Builder plan or above, Base44 syncs code with GitHub in both directions on the main branch, and the project can be exported as a ZIP. We work in that repository, with test data rather than your live records, and publish through Base44 as a checked step, so you can keep building in the editor.
If the app needs to leave, we tell you after the review what that costs and what it buys. The front end moves easily; the back end is rebuilt, and the data moved with it, in steps that keep the app running.

A free 20-minute call
You show us the Base44 app and tell us what is going wrong. We say what we expect to find, and whether a paid check is worth it yet.
-
Quick Security Check or App Readiness Review
A senior engineer reads the code and tests the running app: data access, keys, sign-in, payments, deployment.
You get Every finding in writing with its severity and fix; the review adds a keep, change or replace call for each part and a fixed quote.
-
Fixed-price fixes
Security & Data Hardening from $7,500, or Production Launch from $15,000, in your repository, with a test beside each fix.
-
Handover
Production kept apart from development, a deploy you can roll back, and notes so you, the tool or any developer can carry on.

Proof
Who does the work.
A US software engineering firm. The founding team has taken a product off an AI app builder before (built, not yet in paid use) and runs a production telehealth platform on Supabase. We are an independent firm, not a Base44 partner or agency. Across the systems the team built and runs:
- 20,900+ automated tests across the systems the founding team built and runs
- 16,800+ CI runs automated builds and test runs on GitHub Actions
- 940+ merged pull requests across the same codebases

Questions buyers ask
Base44 questions, answered.
Can I move my app off Base44?
The front end, yes: it is a standard React app. Self-hosting the Base44 back end is not documented, so leaving means rebuilding the back end on a standard database and moving the data. We size that after the review; often staying is the better choice.
Can I keep building in Base44 after you fix it?
Yes. We work through the GitHub repository Base44 syncs with, and you keep using the editor. Publishing stays your deliberate step.
Why does checkout do nothing in the editor?
Base44's Stripe checkout runs only on the published app. Test there, with the success and cancel URLs pointing at your real domain.
Will you rewrite everything?
Rarely. The review marks each part keep, change or replace, with the reason, before any work is priced.
Are you affiliated with Base44?
No. Oracis is an independent US software engineering firm. We fix and finish apps built with Base44, alongside apps from Lovable, Bolt, Replit and other tools.
What does it cost to fix a Base44 app?
The first call is free. The Quick Security Check is $495 and its fee is credited toward the App Readiness Review, which is $1,500 flat and credited toward any fix booked within 30 days. Security & Data Hardening is from $7,500 and Production Launch from $15,000, each at one fixed price set after the review. We never bill hourly on work nobody has sized. The full price list.
