Our verdict

Tied #3 of 4 in Self-hosted uptime monitors · If your monitors live in Git

Pros

  • Monitors are text in a YAML file, easy to keep in Git and copy to a new server
  • Small footprint: one container with no database server
  • Any check interval, with the README's advice to give slow checks longer ones

Cons

  • Every change is an edit to the config file; the docs describe no web editor
  • The docs describe only announcements on its status page, with no incident timelines or subscriptions
  • The docs list no database or Docker container checks

Who should skip:Anyone who wants to add and change monitors from a web dashboard.

Rankings and alternatives

Self-hosted uptime monitors scores

Evaluated Nov 7, 2026 Evidence ↓
  • Components to run 4

    4/5 means: One container with storage built in; installing without a container needs a separately installed language runtime or build tool

    One Docker container whose storage defaults to memory, or can be SQLite; the documented way to install without Docker is building it with go install, which needs Go.

  • What it can check 2

    2/5 means: Six of the nine

    HTTP checks with conditions on the body, ICMP, TCP, DNS, certificate expiration, and external endpoints with a heartbeat interval for pushed results make six of the nine. Database queries, Docker container state and server resource use are not documented.

    Rests partly on what the sources don't mention, which is a weaker signal than what they say.

  • Fastest check interval 5

    5/5 means: 15 seconds or less

    The README says Gatus can handle any interval, and the author uses 30 seconds for simple checks used for alerting.

  • Alert channels 4

    4/5 means: 25 to 49

    The README has a configuration section for each of 42 alerting provider types, from AWS SES to Zulip, plus custom alerts.

  • Public status pages 1

    1/5 means: None or one of the five

    Announcements can be shown at the top of the status page. Maintenance windows are documented only as a way to stop alerts, and several status pages, custom domains per page and subscriptions are not documented.

    Rests partly on what the sources don't mention, which is a weaker signal than what they say.

  • Ways to manage monitors 1

    1/5 means: One of the five

    Monitors are defined in a YAML configuration file. The API is read-only, and no web editor or import and export of monitors is documented.

    Rests partly on what the sources don't mention, which is a weaker signal than what they say.

  • Sign-in and users 3

    3/5 means: Two of the four

    The dashboard can be protected with Basic authentication or OpenID Connect, with an optional list of allowed subjects. Two-factor login and user roles are not documented.

  • Getting data out 4

    4/5 means: Three of the four

    Prometheus metrics at /metrics, a read-only API for endpoint status and history, and SVG badges. API keys separate from the login are not documented.

  • Database choices 3

    3/5 means: A built-in database or one kind of database server

    Storage can be memory, SQLite or PostgreSQL, so a built-in database or one kind of server.

  • “Gatus is a developer-oriented health dashboard that gives you the ability to monitor your services using HTTP, ICMP, TCP, and even DNS queries as well as evaluate the result of said queries by using a list of conditions on values like the status code, the response time, the certificate expiration, the body and many others.”
