Open Headers Daniel T מאת

Intercept and rewrite HTTP traffic in real time, record full browser sessions, and sync rule sets with your team through Git — everything runs locally, nothing leaves your machine.

Inject or remove any request/response header on the fly. Block or redirect URLs by pattern. Inject scripts and CSS into any page. Header values can be pulled dynamically from local files, env variables, or HTTP endpoints — useful when you need tokens or config that change between environments.

Recording goes beyond a network tab: it captures requests, console output, DOM events, and storage changes together in one seekable timeline. Export to JSON for programmatic replay or video to drop in a bug report.

Team sync works through any Git repo — commit your rule sets, branch per environment, and share a join link. Secrets stay encrypted on each machine; only the rule structure gets committed.

No telemetry. No account. No cloud. MIT licensed and fully open source.
