Api Perf Analyzer

lazymac2x/api-perf-analyzer-api

A performance testing tool for REST APIs built on Cloudflare Workers. The source repository doesn't reveal specific operations or endpoints, but given the name and infrastructure choice, this appears designed to run distributed API benchmarks from Cloudflare's edge network. You'd reach for this when you need latency measurements from multiple geographic regions or want to stress test endpoints without spinning up your own infrastructure. The streamable HTTP transport means it works over standard web protocols. Worth noting this is a fresh repository with minimal documentation, so expect to dig into the code or wait for the author to flesh out examples and usage patterns.
