  1. 01

    Uptime Kuma

    open sourceMITSelf-host
    87kaug 2026

    A cheerful dashboard for asking URLs whether they are dead yet.

    The catch vs Better Stack

    It 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-host
    12kjul 2026

    A YAML file, a status board and enough protocol checks to annoy most outages.

    The catch vs Better Stack

    It 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.

    OpenStatus

    open sourceAGPL-3.0Local or hosted
    8.9kaug 2026

    Uptime checks and a status page, with YAML for the suspicious.

    The catch vs Better Stack

    It 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 hosted
    7.4kaug 2026

    Uptime, status pages and on-call in one enormous open-source cupboard.

    The catch vs Better Stack

    It 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.

    Kener

    open sourceMITSelf-host
    5.1kaug 2026

    A handsome status page that also does the checking, not just the apologizing.

    The catch vs Better Stack

    It 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.
