Deploy and Host Changedetection.io on Railway

Changedetection.io is a self-hosted website change detection and notification service. It monitors web pages for content changes—tracking price drops, restocks, content updates, and API modifications—then sends instant alerts via Discord, Slack, Email, Telegram, or webhooks.

About Hosting Changedetection.io

Hosting Changedetection.io requires a containerized deployment with persistent storage for watch configurations and notification history. The application runs as a Python-based web service on port 8080, storing all data in a /datastore directory. For JavaScript-heavy websites, this template includes SockpuppetBrowser for full page rendering via private networking. Railway's single-volume architecture works well here since all application data consolidates under one mount point.
