Webfree

Uptime is a free, self-hosted uptime monitor built as a single Node.js app, positioned as a lightweight alternative to Uptime Kuma, Healthchecks.io, Gatus, Statping, and Better Stack. It checks HTTP/HTTPS, TCP, ICMP, and DNS, watches TLS certificate and domain WHOIS expiry, accepts passive heartbeat pings for cron jobs, and sends alerts to Discord, Slack, Telegram, and other webhooks, with SQLite or MySQL storage.
