Building a internal tool with Cloudflare? Let us review it.
Expert code review for internal tools built with Cloudflare. We fix Cloudflare-specific security gaps, optimize performance, and handle deployment. From $19.
Common Cloudflare issues we find
Real problems from Cloudflare codebases we've reviewed.
Node.js API incompatibility
Code using Node.js-specific APIs (fs, Buffer, crypto) that don't exist in the Cloudflare Workers runtime, causing deployment failures.
Missing security headers
No Content-Security-Policy, X-Frame-Options, or HSTS headers configured, even though Cloudflare makes them easy to add via Workers or page rules.
KV storage race conditions
Cloudflare KV is eventually consistent. Code that reads-then-writes without accounting for propagation delays causes data loss and stale reads.
Worker size limits exceeded
Bundled Workers exceeding the 1MB compressed size limit due to large dependencies, preventing deployment.
Internal Tool challenges to solve
Key internal tool concerns that AI-generated code often misses.
Access control
Who can see what? Internal tools need role-based access — finance sees revenue data, support sees customer data, engineering sees system metrics. AI tools build the dashboard but rarely implement granular permissions.
Data sensitivity
Internal tools often connect directly to production databases. A bug that deletes records or a missing auth check that exposes customer PII can have serious legal and business consequences.
Network security
Internal tools should be behind a VPN or protected network, not on the public internet. AI tools deploy to public URLs by default. Proper network configuration prevents external access.
Audit logging
When someone modifies data through an internal tool, you need to know who did what and when. This is essential for debugging, compliance, and accountability.
What we check
Key areas we review for Cloudflare internal tool projects.
Access control — role-based permissions enforced server-side
Database security — read-only where possible, protected write operations
Network configuration — not publicly accessible, VPN or auth gateway
Audit logging — who did what, when
