Description
Forwards webhooks from Request Catcher to localhost with faithful HTTP replay of methods, headers, and body. Tab Tunnel turns any open tab on Request Catcher into a seamless local webhook tunnel for your development workflow — no ngrok, no port forwarding, and no third-party reverse tunnel daemons required. While your Request Catcher tab remains open, incoming webhooks received on your subdomain are captured in real time and faithfully replayed (preserving HTTP method, path, headers, and request body) directly to your local development server (e.g., http://localhost:3000). KEY FEATURES • Faithful HTTP Replay: Replays exact HTTP methods (POST, GET, PUT, PATCH, DELETE, etc.), paths, headers, and payload bodies. • Zero External Dependencies: Runs entirely within your browser — no accounts, CLI daemons, or tunneling subscription limits. • Live Activity Monitor: Built-in popup display showing HTTP response status, millisecond latency, headers, and payload previews. • Integrated Test Trigger: Send sample HTTP POST requests directly from the popup to verify your local endpoint instantly. • Instant Toggle: Enable or disable forwarding at any time with a single click. HOW TO USE 1. Open your subdomain on Request Catcher (e.g., https://my-service.requestcatcher.com). 2. Click the Tab Tunnel icon in Chrome and set your local target URL (e.g., http://localhost:3000). 3. Keep the forwarding toggle enabled. 4. Point your webhook provider (Stripe, GitHub, Shopify, Discord, Slack, etc.) to your Request Catcher URL. 5. All incoming webhooks will be delivered straight to your local application! PRIVACY & SECURITY Tab Tunnel does not collect, track, or transmit your data to any remote servers. Webhook traffic is relayed strictly between Request Catcher and your configured local server (localhost / 127.0.0.1). User preferences and recent logs reside exclusively in your browser's local storage. PERMISSIONS • storage: Used to save your target localhost URL and recent delivery history locally. • http://localhost/* and http://127.0.0.1/*: Host permissions required to deliver webhooks to your local machine. • https://*.requestcatcher.com/*: Content script matching pattern to listen to incoming webhook socket events. SUPPORT & OPEN SOURCE Tab Tunnel is open source. If you have questions, feedback, or need help, check out the project repository on GitHub.
