Cookie DevTools

Developer-focused cookie manager with real-time monitoring, environment profiles, and export.

Cookie DevTools is a developer-focused cookie manager built for debugging, testing, and environment switching. Unlike basic cookie editors, Cookie DevTools gives you the tools developers actually need: a real-time monitor that shows cookie changes as they happen, environment profiles to save and switch between cookie states, and one-click export to curl, cookie files, or raw headers.
