Description
Inject request headers and cookies per match pattern. Switch each rule on and off. CookieJab injects the request headers and cookies you define into the sites you choose, so you can test a staging environment, a feature flag, or an authentication token without touching your real browsing session. Group related rules into a bundle, toggle a whole group at once, or paste a curl command and pick straight from its headers and cookies. Values stay hidden by default. Open source, no analytics, nothing sent anywhere but the sites your rules target.
