ReqTune

Change HTTP request and response headers, or block requests, on the URLs you choose, in groups you switch on and off.

ReqTune sets HTTP request headers on the URLs you choose, in groups you can switch on and off, right from Chrome's side panel. Use it to point an app at staging, send a feature-flag or debug header, add an Authorization token while you develop, or tag every request from one tab. HOW IT WORKS 1. Click the ReqTune icon to open the side panel. 2. Click New group, then enter a URL pattern, a header name and a value. 3. Matching requests now carry the header. Use the switch to pause the group. FEATURES • Groups: pair URL patterns with the headers to send, and turn each group on or off. • Wildcard patterns: *.example.com/api/*, localhost:3000, /graphql and more. • Instant: changes apply as you type. Chrome sets the headers natively, with no JavaScript in the request path. • URL patterns or tabs: target URL patterns, or switch a group to Tabs to send its headers on every request from the tabs you pick. • Priority you control: when groups set the same header, the one higher in the list wins. • Screen-share safe: values of Authorization, Cookie and other token-like headers show as dots until you reveal them. • Comfortable editing: header name suggestions, duplicate groups, undo for deletes, and keyboard shortcuts for adding and removing rows. • Side panel or full page: keep the panel open while you browse, or open it as a full page for long values. Edits stay in sync. • Light and dark themes follow your system. PATTERN SYNTAX [scheme://]host[:port][/path], where * matches any characters. • example.com: every URL on that site • *.example.com: the site and all its subdomains • api.example.com/v1/*: everything under /v1/ on that host • localhost:3000: only port 3000 • https://example.com/*: HTTPS requests only PRIVACY • Your groups are stored locally in the extension's storage. • ReqTune makes no network requests and collects no data. • Header values, tokens included, are stored unencrypted in local extension storage. PERMISSIONS • Access to all sites: lets ReqTune set headers on whichever sites your patterns name. You can limit this in the extension's Chrome settings. • Storage: saves your groups. • Side panel: shows the interface. Requires Chrome 116 or later.
