Browser extension to modify headers and cookies
5 followers
Header Override is an open-source browser extension for modifying request and response headers and cookies with local, URL-scoped rules, and switchable profiles. Test APIs, staging environments, authentication, feature flags, and customer-specific behavior without changing your code. Create profiles for different projects and environments, then switch between them instantly. No account, tracking, analytics, remote code, or external servers.
the local-only approach is honestly refreshing, especially the URL-scoped rules. feels like it was built by someone who actually deals with the headache of switching between staging environments all day.
@vanessa_lam that’s what I was aiming for. Switching between staging environments was one of the main reasons I built the URL-scoped rules and local-only workflow. Thanks for noticing!
The local rules and instant profile switching make this way cleaner than juggling browser flags. Genuinely useful for testing auth flows and staging endpoints without touching code.
@godricgryffindor Thanks so much! That’s exactly the workflow I had in mind—quickly switching profiles and testing auth or staging behavior without changing application code. Glad you find it useful!
