# Open Headers documentation

> The open-source DevToolkit for live browser traffic — rules, API client, network inspection, workspaces, and self-hosted sync.

Open Headers is an open-source DevToolkit that lives where your traffic
is: a browser extension with rules over live requests, a DevTools-grade
network panel, a full API client, workflows, and an encrypted vault — plus
a desktop companion and a self-hosted server for teams that want
git-backed sync and shared workspaces without a cloud in the middle.

Local-first by design: no account, no cloud relay, no telemetry from the
server, and your data stays on your machines. Every feature is in the
free tier; paid plans only add team seats.
