The picks

Uptime Kuma
open sourceMITSelf-host87kaug 2026A cheerful dashboard for asking URLs whether they are dead yet.
The catch vs PingdomIt is excellent for checks from your own server, but has no built-in worldwide probe fleet or polished synthetic transaction recorder.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- Docker Compose with a persistent `/app/data` volume, or a manual Node.js plus PM2 install
- setup
- It still needs an always-on host, Docker volume discipline, and outbound notification credentials; network filesystems are explicitly unsupported for the data directory.
- your data
- Monitor configuration, users, status pages, certificates, and history live in the application database under the mounted `/app/data` directory.

Gatus
open sourceApache-2.0Self-host12kjul 2026A YAML file, a status board and enough protocol checks to annoy most outages.
The catch vs PingdomIt is configuration-driven and normally probes from one place, so Pingdom's global probe network and recorder-style transaction checks are the major losses.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- Run one binary or Docker container and supply a YAML configuration; Helm is available
- setup
- The first hurdle is writing YAML for endpoints, conditions, alerts, and secrets; without configuring a database, history disappears on restart.
- your data
- Monitor definitions live in YAML; results are in memory by default or persist in SQLite or PostgreSQL when storage is configured.

OneUptime
open sourceApache-2.0Local or hosted7.4kaug 2026Uptime and browser transactions with incidents attached; deployment is not tiny.
The catch vs PingdomIt can run uptime and browser checks, but deployment is much heavier and it does not deliver Pingdom's effortless managed global checking footprint.
Install, platforms & data +
- platforms
- webself-hostedself-host, real ops
- install
- Hosted signup, or the release-branch Docker Compose stack; Helm is the production path
- setup
- The recommended self-hosted footprint is large and production requires secrets, TLS, backups, database care, and frequent upgrades rather than a single lightweight monitor.
- engines
- Its AI features can connect to OpenAI, Azure OpenAI, Anthropic, Groq, Mistral, Ollama, and OpenAI-compatible servers such as vLLM, LocalAI, or LM Studio.
- your data
- Self-hosted telemetry is stored in ClickHouse, application state and configuration in PostgreSQL, and cache, queues, and sessions in Redis.
