Description
Fix CORS errors and edit HTTP headers for local development. Minimal permissions, no tracking, no remote code. 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.
