Built with Codex CLI? Deploy it to Firebase Hosting.
Step-by-step deployment help for Codex CLI-built apps on Firebase Hosting. We fix deployment issues, configure Firebase Hosting correctly, and get your app live in production. From $19.
Codex CLI issues we fix before deploying
Problems specific to Codex CLI's code generation that affect Firebase Hosting deployments.
API keys and secrets written directly into generated source files
Codex CLI generates code with placeholder credentials that developers often replace with real values inline, leaving secrets committed to version control. There is no .env scaffolding or secret management setup by default.
No authentication or authorization on generated API endpoints
When Codex generates Express or FastAPI backends, routes are created without middleware for authentication, meaning every endpoint is publicly accessible immediately after deployment.
Single-file output breaks apart for any real project structure
Codex frequently outputs all logic into one or two files rather than organizing code into modules, services, and utilities — making the result hard to maintain and extend as the codebase grows.
Generated code lacks awareness of existing project context
Because Codex operates from a prompt without full codebase indexing, it generates code that duplicates existing utilities, ignores established conventions, and introduces conflicting patterns alongside your real code.
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 Codex CLI-built app to Firebase Hosting?
Yes. We regularly deploy Codex CLI-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 Codex CLI projects typically have?
Codex CLI projects commonly have api keys and secrets written directly into generated source files and no authentication or authorization on generated api endpoints. 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 Codex CLI project live on Firebase Hosting?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Codex CLI-built projects targeting Firebase Hosting, the typical path is: fix Codex CLI-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 Codex CLI app to Firebase Hosting?
Yes. We handle end-to-end deployment: auditing your Codex CLI 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).
