# Go-Upkeep
|
|
|
|
Self-hosted uptime monitor with a TUI you can access over SSH. No browser, no install on the client — just `ssh -p 23234 your-server`.
|
|
|
|
Built on the foundation of [RDGames/go-upkeep](https://github.com/RDGames/go-upkeep).
|
|
|
|
## What it does
|
|
|
|
- **6 check types**: HTTP, Push (heartbeat), Ping, Port, DNS, Groups
|
|
- **9 alert providers**: Discord, Slack, Email, Ntfy, Webhook, Telegram, PagerDuty, Pushover, Gotify
|
|
- **Config as code**: define monitors in YAML, apply declaratively, version control your setup
|
|
- **HA clustering**: leader/follower with automatic failover
|
|
- **Prometheus metrics**: `/metrics` endpoint for Grafana dashboards
|
|
- **Public status page**: HTML + JSON, toggle with an env var
|
|
- **SQLite or Postgres**: SQLite for single-node, Postgres for production
|
|
- **Uptime Kuma import**: migrate from Kuma with one command
|
|
|
|
## Quick start
|
|
|
|
```bash
|
|
go run cmd/goupkeep/main.go
|
|
ssh -p 23234 localhost
|
|
```
|
|
|
|
Seed some demo data to see it in action:
|
|
|
|
```bash
|
|
go run cmd/goupkeep/main.go -demo
|
|
```
|
|
|
|
