Common Firebase Studio issues affecting integrations
Firestore security rules too permissive by default
Firebase Studio frequently generates Firestore rules that allow authenticated users to read and write any document in the database, without scoping access to documents owned by that user.
Client-side security logic that can be bypassed
Access control checks are placed in frontend React components rather than Firestore rules or Cloud Functions, allowing users to bypass restrictions by making direct Firestore SDK calls.
Cloud Function cold start latency degrading UX
Infrequently-called Cloud Functions take 2-5 seconds to cold start, causing noticeable delays on first API calls and making the app feel slow during low-traffic periods.
Resend issues we find in Firebase Studio apps
API key exposed in client-side code
AI-generated code calls the Resend API directly from the browser, exposing the API key and allowing anyone to send emails from your domain.
Sending from unverified domain
Generated code sends emails from a domain that hasn't been verified in Resend's dashboard, causing all emails to fail or land in spam.
No rate limiting on email-sending endpoints
AI tools create API routes that call Resend without any rate limiting, allowing attackers to abuse your endpoint to send thousands of spam emails on your account.

Frequently asked questions
Can you review my Firebase Studio-built Resend integration?
Yes. We regularly audit Resend integrations in Firebase Studio-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Resend issues does Firebase Studio typically create?
Common issues in Firebase Studio-generated Resend code include: api key exposed in client-side code, sending from unverified domain, no rate limiting on email-sending endpoints. We fix all of these in our code review.
How much does it cost to fix my Resend integration?
Start with our code audit ($19) to get a complete list of Resend issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What Resend best practices does Firebase Studio typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for Resend. Our review checks all of these and provides specific fixes.
