HeaderCraft: Header & CORS Editor

IHeaderCraft lets you edit HTTP request and response headers right in the browser: fix CORS errors and inject test auth tokens in seconds, without touching backend code. WHAT IT DOES - Add, edit, or remove request headers (e.g. an Authorization token for local testing) - Fix CORS instantly by setting response headers like Access-Control-Allow-Origin - Scope rules to one site or apply them everywhere - Flip everything on or off with one master switch WHY INSTALL IT The last popular header editor, ModHeader (1.6M users), was pulled by Google and Microsoft in July 2026 after a hidden, remotely-activatable browsing history collector was found inside it. HeaderCraft is a safer replacement: no history access, no analytics, no remote code. Every rule you create is visible and auditable, and nothing leaves your device. Trusting it with all-sites access is actually safe. FREE, WITH AN OPTIONAL UPGRADE Free for up to 3 rules. Need more? HeaderCraft Pro is a one-time purchase (no subscription) for unlimited rules, plus export/import to reuse or share a rule set. WHO IT'S FOR Developers, QA engineers, and anyone testing APIs locally.
