Overview

Modify browser request and response headers, cookies, and redirects with flexible filters and agent-friendly automation.

HeaderKit is a privacy-friendly tool for modifying HTTP request and response headers directly in Chrome. Create profiles to organize request headers, response headers, cookies, and redirects. Apply rules only to selected URLs, tabs, windows, or resource types. Rules can be enabled individually, paused globally, and imported from or exported to JSON. HeaderKit also supports importing ModHeader configurations and optional automation through the HeaderKit CLI. All configuration is stored locally. HeaderKit has no accounts, telemetry, advertising, or developer-operated servers. Agent Mode is disabled by default and connects only to a CLI process started by the user on the same computer. https://github.com/GeoffZhu/HeaderKit
