    • TL;DR

    Gatus is a self-hosted uptime monitor and status page for small infrastructure teams that want checks defined in configuration. It replaces simple hosted uptime tools when Apache-2.0 licensing, HTTP/TCP/ICMP/DNS checks, and a built-in status page are enough.Apache-2.0 · Go · 11.2K stars · Active this week

    who it's for

    Who Gatus is for#

    Small teams publishing service health

    Gatus fits teams that need endpoint checks plus a simple status page from a config file.

    Skip if:

    Use a managed status platform if external SLAs, subscribers, and incident comms are the main need.

    Developers monitoring internal services

    Gatus can watch APIs, ports, DNS, and other checks that a generic website monitor may not cover.

    Skip if:

    Skip it if you need deep APM, traces, or log analytics.

    the problem

    The problem it solves#

    how Gatus solves it

    How it solves it#

    Multiple check types

    Gatus supports HTTP, TCP, ICMP, DNS, and custom-style health checks, covering more than simple website ping monitoring.

    Configuration-as-code

    Checks live in configuration, which makes monitoring changes reviewable and repeatable across environments.

    Built-in status page

    Gatus includes a public status-page view, so teams can expose service health without adding a separate status-page product.

    strengths · trade-offs

    Strengths and trade-offs#

    Strengths

    • Simple self-hosted monitoringGatus is strong when a team wants lightweight uptime monitoring under its own control instead of a large observability platform.
    • Readable operational configConfiguration files make health checks visible in code review, which helps teams understand what is actually monitored.

    Trade-offs

    • -Not full observabilityGatus does not replace metrics, tracing, log search, or incident-management platforms. It answers health-check questions well.
    • -Self-hosted monitor needs placementA monitor running inside the same network can miss external user-facing failures. Teams may need external probes or multiple deployments.

    Hosted uptime tools are easy to start, but teams often outgrow basic ping checks. They need endpoint assertions, DNS checks, internal service visibility, and a status page that reflects what they actually monitor.

    Small teams also want monitoring config in version control, not a set of hidden dashboard clicks that no one can review after an incident.

    Gatus is Apache-2.0 licensed.
