Deploy and Host webhook-catcher on Railway

webhook-catcher is a lightweight FastAPI-based tool to receive, view, debug, and replay webhooks with a clean HTML UI. It includes features like search, filtering, dark mode, and replay support — perfect for testing integrations and inspecting webhook payloads in real-time.

⚠️ Railway Volume Setup (Important)

webhook-catcher uses SQLite to store received webhook payloads.

On Railway, filesystem storage is ephemeral by default.
This means all webhook data will be lost on every redeploy unless a persistent volume is attached.

To persist webhook data across redeploys, you must add a Railway Volume.

Required Steps on Railway

Deploy the project (template or repository)
Go to Your Service → Volumes
Click Add Volume
Mount the volume to: /app/data
Redeploy the service

Once the volume is mounted, SQLite data will persist normally across redeploys.

❗ Without a mounted volume, webhook logs will be wiped every time the service restarts or redeploys.
