proxy-benchmark is a reproducible measurement harness that isolates whether a failed web request is caused by the proxy, browser fingerprint, target, or the host machine itself. It runs controlled experiments across HTTP clients, Chromium variants, anti-detect browsers, and proxy paths, logging every attempt as JSONL evidence with generated tables and statistical tests. The project is notable for treating debugging claims as falsifiable experiments and for surfacing non-obvious findings like host machine variance and Chrome's 43 MB of background traffic per profile.

Target audience: web scraping engineers, proxy users, browser automation developers, anti-bot researchers
