The picks
5 open source · ranked by fit
- 01
Uptime Kuma
open sourceMITSelf-host87kaug 2026A cheerful dashboard for asking URLs whether they are dead yet.
The catch vs Better StackIt is simple and friendly, but checks originate from infrastructure you operate and there is no managed multi-region fleet or full on-call service.
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 Better StackIt is compact and capable, but lacks the managed multi-region probe network, turnkey escalation, and zero-maintenance reliability of Better Stack or UptimeRobot.
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.
- checked

- 03
OpenStatus
open sourceAGPL-3.0Local or hosted8.9kaug 2026Uptime checks and a status page, with YAML for the suspicious.
The catch vs Better StackIt is a close open alternative, but its global-check coverage, incident ecosystem, and operational maturity remain thinner than the established paid services.
Install, platforms & data +
- platforms
- webself-hostedcliself-host, real ops
- install
- Hosted signup, or the project's Docker Compose/Coolify self-host stack
- setup
- The full self-host path is several services, not one monitor, including migrations, workflows, API, dashboard, status-page frontend, checker/private locations, database, and authentication/email secrets.
- your data
- Self-hosting uses a LibSQL/Turso-compatible relational database for application state; optional Tinybird stores analytical check data, with mounted volumes for local services.

OneUptime
open sourceApache-2.0Local or hosted7.4kaug 2026Uptime, status pages and on-call in one enormous open-source cupboard.
The catch vs Better StackIt can replace much of the suite, but doing so means operating a large observability and incident stack instead of buying a small managed monitor.
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.
- checked
- 2026-08-14
- 05
Kener
open sourceMITSelf-host5.1kaug 2026A handsome status page that also does the checking, not just the apologizing.
The catch vs Better StackIt is strongest as an attractive status page with checks, not as a mature worldwide synthetic-monitoring and on-call service.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- Docker Compose with Kener and Redis; PostgreSQL or MySQL can replace the default SQLite database
- setup
- A usable deployment needs Redis plus a secret key, public origin, persistence, and mail/notification settings, so it is not a one-container static status page.
- your data
- Configuration and incidents default to `./database/kener.sqlite.db`, with PostgreSQL/MySQL supported; Redis carries queues, cache, and scheduled jobs.
