RequestLoom — Headers & Redirects

Manage request and response headers and domain redirects with switchable profiles.

RequestLoom helps web developers and QA engineers manage HTTP header changes and domain redirects through reusable profiles. FEATURES • Set or remove request and response headers. • Redirect requests from a source domain to another host, port, or HTTP(S) scheme while keeping the path and query. • Organize rules into named profiles and enable multiple profiles together. • Limit header rules to exact domains or wildcard subdomains. An empty domain list applies to all sites. • Drag profiles to control priority: profiles lower in the list win conflicts. • Toggle profiles from the popup or pause all rules without losing their settings. • Export a single profile or your full configuration as JSON, and import profiles without replacing existing ones. • Sync configuration through Chrome Sync. USE CASES Switch development environments, add test headers, debug API integrations, and redirect development traffic to a local service. DATA AND PRIVACY RequestLoom has no developer-operated backend, advertising, analytics, or telemetry. Rules are applied by Chrome's declarativeNetRequest API. Configuration, including header values you enter, is stored using chrome.storage.sync and may sync through your Google account according to your Chrome settings. JSON exports contain your configured values, so review them before sharing. Only enable rules for sites you intend to test. No separate RequestLoom account is required.
