Summary: Vigilant is a self-hostable website monitoring tool that goes beyond simple uptime checks. It covers uptime from multiple locations, broken link detection, Google Lighthouse/performance tracking, SSL certificate monitoring, DNS change alerts, CVE/security tracking, and flow monitoring (automated testing of real user journeys like logins or checkouts). Notifications are supported via Slack, Discord, Email, MS Teams, Telegram, Ntfy and others.

Notes: The project is open source, built in Europe, and already ships with a Docker Compose setup, making it a straightforward candidate for a Cloudron package. The stack includes the main app, a Horizon worker, a Lighthouse container, MySQL 8 and Redis. Deployment docs: https://govigilant.io/documentation/deployment
