Building a real-time app with Netlify? Let us review it.
Expert code review for real-time apps built with Netlify. We fix Netlify-specific security gaps, optimize performance, and handle deployment. From $19.
Common Netlify issues we find
Real problems from Netlify codebases we've reviewed.
Missing redirect rules for SPAs
Single-page apps without a _redirects file or netlify.toml rewrite rules, causing 404 errors when users navigate directly to routes.
Environment variable misconfiguration
Build-time vs runtime environment variable confusion, or sensitive keys set in the wrong context (deploy previews, branch deploys).
Serverless function cold starts
Netlify Functions with large dependencies or no connection pooling, causing timeout errors on the first invocation after idle periods.
Missing build optimization
No caching configured for node_modules or build artifacts, causing unnecessarily long build times and deployment delays.
Real-time App challenges to solve
Key real-time app concerns that AI-generated code often misses.
Connection management and reconnection
WebSocket connections drop constantly — network switches, phone sleep, server deploys. AI tools open a connection but don't handle disconnection, reconnection, or missed messages during downtime. Users see stale data or lose messages without knowing it.
Message ordering and delivery guarantees
Messages must arrive in order and must not be lost. Network issues can deliver messages out of sequence or duplicate them. AI-generated real-time code has no message ordering, no deduplication, and no delivery confirmation — which means lost messages and confused users.
Conflict resolution in collaborative editing
When two users edit the same content simultaneously, whose changes win? AI tools implement 'last write wins,' which silently discards one user's work. Production collaboration needs operational transforms or CRDTs to merge concurrent edits correctly.
Scaling concurrent connections
Each WebSocket connection holds server resources. A single server can handle hundreds of connections, but thousands require load balancing with sticky sessions, a pub/sub layer (like Redis), and horizontal scaling. AI tools don't implement any of this.
What we check
Key areas we review for Netlify real-time app projects.
Connection lifecycle — reconnection logic, heartbeat, graceful degradation
Message delivery — ordering guarantees, deduplication, acknowledgments
Authentication — WebSocket connections verified, channel-level authorization
Scaling — connection pooling, pub/sub architecture, horizontal scaling readiness

Frequently asked questions
Can you review a real-time app built with Netlify?
Yes. We regularly audit Netlify real-time app projects and understand the specific patterns and pitfalls of this combination. Our review covers security, performance, and deployment readiness.
What issues do you find in Netlify real-time apps?
Common issues include missing redirect rules for spas and environment variable misconfiguration on the Netlify side, combined with real-time app-specific concerns like connection management and reconnection and message ordering and delivery guarantees. We check for all of these and more.
How do I make my Netlify real-time app production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Netlify real-time app projects, the typical path is: fix security gaps, address real-time app-specific requirements, optimize Netlify performance, then configure deployment. We provide a fixed quote after the audit.
How long does it take to audit a Netlify real-time app?
Our code audit delivers a full report within 24 hours. For Netlify real-time app projects, we check security, architecture, performance, and deployment readiness across all Netlify-specific patterns. Fixes are scoped separately with a fixed quote.
