About Header Editor Pro – Modify HTTP Headers
Modify HTTP request and response headers. Unlimited profiles, domain and tab group filters, 7 languages. Free and open source.
Header Editor Pro is a free, open source HTTP header editor for developers. Add, modify or remove request and response headers, with no account, no telemetry and no limits.
WHAT IT DOES
• Request and response headers — set or append, each one individually toggleable • Unlimited profiles — no three-profile ceiling • Domain filters — scope a profile to the domains you choose • Tab group filters — keep sandbox headers inside their tab group, so staging headers never reach production tabs • Concurrent profiles — different tab groups can carry different headers at the same time • Pause everything with one click, without losing your configuration • Import and export profiles as JSON • 7 languages: English, Español, 日本語, 한국어, Русский, 简体中文, 繁體中文
TYPICAL USES
• API testing — send Authorization: Bearer <token> to authenticated endpoints • CORS debugging — add Access-Control-Allow-Origin to reproduce and diagnose • Environment switching — X-Environment: staging against a different backend • Device testing — change User-Agent to compare mobile and desktop responses
PRIVACY
No data collection, no analytics, no telemetry, no external servers. Your configurations live in local browser storage and never leave your machine. Header rules are applied by the browser itself through the declarativeNetRequest API — the extension does not read page content, and never sees the requests it modifies.

FREE, AND NOBODY PAYS FOR IT
No paywall, no "pro" tier, no nag screens. Nobody funds this work. If you want something improved, open an issue on GitHub and let's talk it through.

Data source
Covers every Chrome Web Store extension with at least 100 users, found through the store's public sitemap. User counts are read from public listing pages. The 10% most-used extensions are refreshed daily, the next 40% weekly and the next 40% monthly; the least-used 10% are not refreshed. Google displays rounded user counts (and caps the display at 10,000,000+), so small changes may not be visible. Rating counts above 1,000 are rounded (e.g. 1.6K).
