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.

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#

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.

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.
