# Uptime Kuma
|
||||
|
||||
# Features
|
||||
|
||||
* Monitoring uptime for HTTP(s) / TCP / Ping.
|
||||
* Fancy, Reactive, Fast UI/UX.
|
||||
* Notifications via Webhook, Telegram, Discord and email (SMTP).
|
||||
* 20 seconds interval.
|
||||
|
||||
# How to Use
|
||||
|
||||
npm
|
||||
|
||||
Docker
|
||||
|
||||
One-click Deploy to DigitalOcean
|
||||
|
||||
# Motivation
|
||||
|
||||
* I was looking for a self-hosted monitoring tool like "Uptime Robot", but it is hard to find a suitable one.
|
||||
* Want to build a fancy UI.
|
||||
* Learn Vue 3 and vite.js.
|
||||
* Show the power of Bootstrap 5.
|
||||
* Try to use WebSocket with SPA instead of REST API.
|
||||
* Deploy my first Docker image to Docker Hub.
|
||||
|
||||
|
||||
If you love this project, please consider giving me a ⭐.
