Competitors overview
Requestly
Full‑featured rules platform (headers, redirects, mocks, scripts). Great for complex flows, but heavier if you only need request header changes.
Header Editor (browser extension)
Flexible rules for headers plus redirect/cancel. Useful for power users; less specialized for quick header‑only edits.
Desktop proxies (Charles, Fiddler Everywhere, Proxyman)
Capture and rewrite traffic across apps and devices, not just in the browser. Ideal for QA and cross‑app debugging; more setup and usually paid.
FAQ
📂 Can I export and version control configs?
Share links encode headers in the URL. Paste them into docs or copy the JSON directly.
🔒 Does the share page send my data anywhere?
No. Everything stays in your browser. Sensitive keys are automatically masked.
🌐 Will my rules apply to all sites?
Use per‑site scopes to keep rules local and avoid header leakage.
🔧 What if I need redirects or mocks?
For complex needs, try Requestly or desktop proxies. For headers only, VibeHeader is simpler.
🛡️ Security tips?
Share only with trusted teammates, avoid long-lived secrets, rotate values periodically.
