About Nezha

Nezha is a self-hostable monitoring and O&M tool for servers and websites, written in Go. It tracks system status for your machines and checks websites, including changes to or the expiry of SSL certificates, over HTTP, TCP and ping.

Beyond status checks, it can push alerts to notification channels, run scheduled tasks on monitored servers and open a web terminal to them. It has a user-facing dashboard and an admin backend, and the community offers alternative themes for the public front end. Documentation is available in English and Chinese, and translations are managed on Hosted Weblate.

Nezha is released under the Apache-2.0 licence and run on your own server. It is aimed at individuals, hobbyists and small teams that want a simple status page and light remote management of a handful of servers rather than a heavyweight observability stack.
