AnyHook
Open source webhook IDE for developers.
Licensed under Apache-2.0
About
Inspect, replay, retry, and relay webhooks from any provider — self-host under Apache 2.0 or use the managed cloud. Point Stripe, GitHub, Shopify, or any provider's webhook at AnyHook and get automatic retries, a full event log, and one-click replay. Change one URL.
AnyHook sits between webhook senders and your application. Cloudflare Workers verify the sender's signature in <50ms at the edge, Upstash QStash handles durable retry and dead-lettering, and a Vercel-hosted dashboard gives you a full event log and one-click replay. The full codebase is open source under Apache 2.0 — self-host the same engine that runs the cloud version. Supports Stripe, GitHub, Shopify, Slack, Linear, Vercel, Discord, Twilio, SendGrid, Sentry, Clerk, Resend, Lemon Squeezy, Paddle, Intercom, HubSpot, WooCommerce, and a growing list.
