About Request Headers

Request Headers lets you add custom HTTP request headers on specific websites — without DevTools. • Per-site rules — configure headers for example.com, *.staging.example.com, and more • Header profiles — switch test states in one click (Free user, Admin, feature flags, etc.) • Export / import — share QA setups as JSON with your team • On-demand site access — headers apply only on sites you explicitly allow • Everything stays on your device — no account, no cloud, no analytics Built for QA engineers and developers who test APIs and web apps in the browser.
