Overview

CheckCle is a self-hosted, open-source monitoring platform for servers, applications and infrastructure. It checks HTTP, DNS, ping and TCP-based services, tracks uptime and response times, records incident history, and sends alerts. It also monitors SSL certificates and domains, collects server metrics through an installable agent, and offers public status pages. It is written in Go and runs in Docker.

Key features

  • Uptime checks for HTTP, DNS, ping and TCP services
  • Distributed regional monitoring and incident history
  • SSL and domain expiry monitoring
  • Server metrics such as CPU, RAM, disk and network via an agent
  • Alerts through email, Telegram, Discord, Slack and Matrix, plus public status pages

Best for

Developers and sysadmins who want to run their own uptime and server monitoring instead of using a hosted service. The README lists Linux servers, with Windows support in beta, on amd64 and arm64.
