uptop

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.

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

go run cmd/uptop/main.go
ssh -p 23234 localhost

Seed some demo data to see it in action:

go run cmd/uptop/main.go -demo

Config as code

Export your current monitors:

Apply a config file:

uptop apply -f monitors.yaml
uptop apply -f monitors.yaml --dry-run   # see what would change
uptop apply -f monitors.yaml --prune     # delete anything not in the YAML
