Requests by Method
Don't just see that a request is slow. See why.
Debugging shouldn't be a guess
A slow API request can hide behind dozens of moving parts. APILens gives you the complete request path so you can find the bottleneck instead of guessing.
This is what your console outputs for every request. Method, route, status, latency, trace ID, and every DB query - automatically.
9 libraries patched, zero setup.

Authorization headers, passwords, tokens, API keys, and cookies are stripped before data leaves your server.
TLS 1.2+ in transit, AES-256 at rest.
Configure which fields are masked and which routes are skipped entirely.
