Webhooks.cc is a free, open-source webhook inspection and testing platform built for developers. Create a unique endpoint URL, point any service at it, and watch requests arrive in real-time — headers, body, query parameters, IP, and timestamps, all formatted and searchable. Signed provider templates — Send realistic test webhooks from Stripe, GitHub, Shopify, and Twilio directly from the dashboard. Signature headers are generated automatically so you can verify your integration end-to-end without waiting for real events. CLI tunneling — Forward incoming webhooks to localhost with whk tunnel . No port forwarding, no ngrok — just a direct stream from your public endpoint to any local port and path you choose. TypeScript SDK — Programmatic access to every webhooks.cc feature. Create endpoints, send templates, and wait for matching requests with composable matchers — built for Vitest, Jest, and CI pipelines like GitHub Actions. MCP server — Connect your AI coding agent — Claude Code, Cursor, VS Code, or Codex — and let it create endpoints, send test webhooks, inspect payloads, and replay requests through natural language. Open source & simple pricing — The entire platform is open-source under AGPL-3.0, with the CLI and SDK available under MIT. The free tier includes 50 requests/day, unlimited endpoints, and full access to the CLI, SDK, and MCP server. Pro ($8/month) scales to 100,000 requests/month with 30-day retention.
