BrowseSprint

BrowseSprint offers a language-independent measurement guide and blank CSV worksheet for developers comparing coding-agent browser workflows. The resource is free and available without signup. Record three baseline and three changed runs with elapsed time, successful outcomes, retries, tool calls and session state. Use the same public page and expected outcome, and retain failed runs when comparing approaches. Guide: https://codexbrowse.site/codex-browser-slow. Editable English/Chinese resource pack: https://github.com/liubrain39/browsesprint-resources. BrowseSprint is an independent research project with an optional waitlist; no extension is released and no verified speedup is claimed.
