Built with GPT Engineer? Deploy it to Firebase Hosting.
Step-by-step deployment help for GPT Engineer-built apps on Firebase Hosting. We fix deployment issues, configure Firebase Hosting correctly, and get your app live in production. From $19.
GPT Engineer issues we fix before deploying
Problems specific to GPT Engineer's code generation that affect Firebase Hosting deployments.
No authentication system
GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.
Direct database access from client
Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.
Incomplete feature implementations
Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.
Missing error boundaries
A single component error crashes the entire application. No error boundaries or fallback UIs to gracefully handle failures.
Firebase Hosting deployment issues we check for
Common Firebase Hosting problems that break AI-generated apps in production.
Firestore security rules allow public read/write
AI tools set Firestore rules to allow read, write: if true for development and never lock them down, exposing the entire database to any authenticated or anonymous user.
Cloud Functions cold start on free Spark plan
Firebase Cloud Functions on the Spark plan have aggressive cold starts and limited concurrency, causing 5-15 second delays on first invocation.
firebase.json rewrites not matching SPA routes
Single-page app routing requires a rewrite rule in firebase.json to send all requests to index.html. AI tools either omit this or misconfigure it alongside Cloud Functions rewrites.
Storage rules expose private user files
Firebase Storage rules generated by AI allow any authenticated user to read any file, rather than restricting access to the file owner.

Frequently asked questions
Can you deploy a GPT Engineer-built app to Firebase Hosting?
Yes. We regularly deploy GPT Engineer-generated projects to Firebase Hosting. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Firebase Hosting.
What Firebase Hosting issues do GPT Engineer projects typically have?
GPT Engineer projects commonly have no authentication system and direct database access from client. When deploying to Firebase Hosting, these combine with platform-specific issues like firestore security rules allow public read/write and cloud functions cold start on free spark plan.
How do I get my GPT Engineer project live on Firebase Hosting?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For GPT Engineer-built projects targeting Firebase Hosting, the typical path is: fix GPT Engineer-specific code issues, configure Firebase Hosting settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my GPT Engineer app to Firebase Hosting?
Yes. We handle end-to-end deployment: auditing your GPT Engineer codebase, fixing deployment blockers, configuring Firebase Hosting correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
