A free, permanent, signed webhook URL you can inspect and replay to localhost — from the CLI, API, dashboard, or MCP.

Webhooks fail quietly. The request arrives once, the signature either checks out or it doesn't, and by the time you know something broke the payload is gone. We keep it — on a stable signed URL that doesn't expire — so you can read exactly what arrived, see whether the signature verified, and replay it at your local server as many times as it takes.
Want to see it work? Open webhook.co/play — send a webhook, watch it land. No signup, nothing to install.
| Repo | What it is |
|---|---|
| webhook | The platform. Ingestion and delivery engine, the wbhk CLI, the MCP server, the TypeScript and Python SDKs, and a Standard-Webhooks signing implementation with a 141-provider signature registry. Apache-2.0. |
| webhook-go | The official Go SDK — typed access to endpoints, events, deliveries and replays, with retries, pagination and secret redaction. |
| homebrew-tap | brew install webhook-co/tap/wbhk |
npx @webhook-co/cli loginOpen core: the ingestion and delivery engine, the CLI and replay client, the MCP server, the SDKs and the signing implementation are Apache-2.0. An open, shared webhook interop standard — not a restrictive license — is the point.
If any of this is useful to you, a ⭐ on webhook-co/webhook helps more than you'd think.
