Install

curl -fsSL https://railhook.io/install.sh | bash

On a server with a domain pointed at it, get HTTPS in the same step:

curl -fsSL https://railhook.io/install.sh | bash -s -- --domain hooks.example.com --email ops@example.com

Already running a reverse proxy? Add --behind-proxy instead of --email. Then point the proxy at 127.0.0.1:8080.

Open http://localhost and register — the first account is active immediately.

• Checks the machine first: Docker with Compose v2, about 4 GiB of RAM, 5 GiB of disk, a free port.
• Writes a Compose file pinned to the latest release and a .env with freshly generated secrets.
• Starts everything behind one port. Day two is ./railhook status | logs | upgrade | backup | doctor.

Rather not run it yourself? Railhook Cloud at https://railhook.io is free right now (10,000 events a month, 3 projects, 7 days of history). Paid plans with support and higher limits will come later.

What it does

Outgoing — your app announces an event; Railhook gets it to every endpoint that subscribed.

• An accepted event is never lost: it is recorded in the same transaction as your write.
• Customers verify every request — Standard Webhooks headers, with secret rotation.
• Failures retry on a schedule that runs for more than a day, then land in Failed Messages for bulk retry.
• Deliveries to one endpoint can arrive in the order the events happened.
• Time Machine replays a past range as fresh deliveries.
• Every attempt is on record with the response it got.

Incoming — a provider posts to a URL you own; Railhook checks it and forwards it on.

• Stripe, GitHub, GitLab, Shopify, Slack, Twilio, Square, Adyen, SendGrid and HubSpot are verified out of the box; generic HMAC covers the rest.
• Each incoming event is kept as it arrived; a provider's repeat of the same event is not forwarded twice.
• Forwards reach your destinations with their own retries and Failed Messages.
