AI App Builder

Base44 security audits and migrations to open infrastructure

Base44 (Wix-acquired) is an AI fullstack app builder with proprietary backend services. The AI is fast, but recent security disclosures and platform outages have made portability a top concern.

Top issues we find auditing Base44 apps

Patterns documented in primary-source security research, community forums, and real-world audits. These are the things that ship to production and break in front of users.

JWT passed to apps via URL

Wiz and Imperva disclosed that Base44 passed the user's main account JWT to apps via the URL, and apps could run arbitrary JS. Any app developer could harvest tokens for full account takeover.

Open redirect leaking access tokens

Confirmed by Imperva's research. Tokens leaked via redirect chains.

Stored XSS in app-generated content

Base44 didn't sanitize user-supplied HTML in entity fields, allowing stored cross-site scripting.

Client-side-only enforcement of premium features

Paid features could be unlocked by editing the client. Backend validation absent.

Entity schema files excluded from 'Freeze Files'

The AI agent overwrites manually-configured RLS rules during publish. Rules silently disappear after every redeploy.

Public API endpoints bypassing auth

Wiz researchers found enterprise app endpoints accessible without authentication.

Default 'everyone can view' on data types

Role permissions are misconfigured by default, persisting on data types that should be admin-only.

Cost & performance gotchas

  • Credit-burning loops in the AI ('dead-end debug loops' reported).
  • No control over scaling. All logic runs through Base44's hosted runtime.
  • Workflows degrade as apps grow.

Thinking of leaving Base44?

We migrate Base44 apps to your own infrastructure starting at From $600. Keep the work, drop the lock-in.

  • Next.js + Supabase + Vercel
  • Next.js + Postgres + Railway

Comparing Base44 to other tools

Founders we've helped on Base44

Jacob has been absolutely fantastic to work with, his communication style and web development knowledge are top notch. He helped me migrate two of my apps off of Base44 in a breeze.

Jacob migrated a pretty complex app that was built in Base 44 for me. He is extremely skilled and knowledgeable. His communication and response times are impeccable! In addition to the migration, I hired him for ongoing support which has been the same pleasant experience! I recommended him to a friend for website development and my friend was extremely happy as well. I highly recommend Jacob!

Frequently asked questions

Are Base44 apps still secure after the Wiz disclosure?
The patched issues (JWT-via-URL, open redirect, stored XSS, public API endpoints) are fixed at the platform level. But individual apps still have role misconfigurations, missing input validation, and rules that get overwritten on redeploy. An audit catches these.
Can I migrate my Base44 app to my own stack?
Yes. We use a combination of the community base44-to-supabase-sdk and manual rebuilds to move your data, schema, and workflows to Supabase + Next.js. From $600.
What happened in the February 2026 outage?
A platform-wide outage stranded thousands of Base44 apps. Apps without GitHub sync (paid-tier only) had no fallback. This is the core reason for migrating off proprietary builders.
