uptop

Self-hosted uptime monitoring with a TUI over SSH.

No browser. No client install. Just ssh -p 23234 your-server.

What is this

An uptime monitor you manage entirely from the terminal. It runs as a server, exposes an SSH endpoint, and drops you into a full TUI — monitors, alerts, logs, nodes, all there.

Built on RDGames/go-upkeep. Rewritten for clustering, config-as-code, and a proper dashboard.

Features

• 6 check types — HTTP, Push (heartbeat), Ping, Port, DNS, Groups
• 10 alert providers — Discord, Slack, Email, Ntfy, Webhook, Telegram, PagerDuty, Pushover, Gotify, Opsgenie
• Config as code — define monitors in YAML, apply declaratively, version control your setup
• HA clustering — leader/follower with automatic failover
• Prometheus metrics — /metrics endpoint, wire it straight to Grafana
• 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

Screenshots

Quick start

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

Want some data to look at first:

go run cmd/uptop/main.go -demo

Install

Docker (recommended)

services:
  uptop:
    image: lerkolabs/uptop:latest
    restart: unless-stopped
    ports:
      - "23234:23234"
      - "8080:8080"
    environment:
      - UPTOP_DB_TYPE=sqlite
      - UPTOP_DB_DSN=/data/uptop.db
      - UPTOP_STATUS_ENABLED=true
      # - UPTOP_ADMIN_KEY=ssh-ed25519 AAAA... you@host
    volumes:
      - ./data:/data

First run: set UPTOP_ADMIN_KEY to your SSH public key, or attach to the container and add it in the Users tab.

Binary (Linux amd64)

Download from Releases.

From source

go install gitea.lerkolabs.com/lerkolabs/uptop/cmd/uptop@latest

Upgrading: Pull the new image (or binary) and restart. Database migrations run automatically on startup.

Config as code

Export your current monitors:

uptop export -o monitors.yaml

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

Environment variables

Variable	Default	Description
UPTOP_PORT	23234	SSH server port
UPTOP_HTTP_PORT	8080	HTTP server port (status page, push, metrics)
UPTOP_DB_TYPE	sqlite	sqlite or postgres
UPTOP_DB_DSN	uptop.db	Database path or connection string
UPTOP_STATUS_ENABLED	false	Enable public status page
UPTOP_STATUS_TITLE	System Status	Status page title
UPTOP_ENCRYPTION_KEY		AES-256-GCM key for alert credentials (details)
UPTOP_CLUSTER_MODE	leader	leader, follower, or probe
UPTOP_PEER_URL		Leader URL for follower and probe nodes
UPTOP_CLUSTER_SECRET		Shared key for cluster + API auth
UPTOP_INSECURE_SKIP_VERIFY	false	Skip TLS verification for checks
UPTOP_ALLOW_PRIVATE_TARGETS	false	Allow monitoring RFC1918/loopback addresses
UPTOP_ADMIN_KEY		SSH public key seeded as first admin on startup

See .env.example for all options including TLS, probes, and advanced settings.

Encryption

Set UPTOP_ENCRYPTION_KEY to encrypt alert credentials (SMTP passwords, webhook URLs, API tokens) at rest with AES-256-GCM. Generate a key:

openssl rand -hex 32

Without this, credentials are stored as plaintext in the database. uptop warns on startup if unset. To encrypt credentials on an existing install, run uptop migrate-secrets with the key set.

Clustering

uptop supports three modes: leader (default single node), follower (HA failover — takes over if the leader goes down), and probe (stateless distributed checks from multiple regions).

See docs/clustering.md for setup guides, or the working examples in deploy/.

Migrating from Uptime Kuma

Export your Kuma backup JSON, then:

curl -X POST http://localhost:8080/api/import/kuma \
  -H "X-Upkeep-Secret: your-secret" \
  -H "Content-Type: application/json" \
  -d @kuma-backup.json
