What is OpenHeader?
OpenHeader is a lightweight, open-source Chrome extension for adding, modifying, and removing HTTP request and response headers. Built for developers, QA, and API testing.
It changes your header rules — and never reads or intercepts your traffic. Header changes are applied through Chrome's official declarativeNetRequest engine, so the extension only declares rules to Chrome and cannot see, log, or transmit your requests.
Features: request/response header editing, multiple profiles, per-URL filters, and import/export. No account required. MIT licensed.
