Gatus checks your endpoints over HTTP, TCP, DNS, ICMP and more, evaluates conditions such as status code, response time or body content, and shows the results on a status page. It is Apache-2.0 licensed and configured entirely in YAML.

## Monitoring as configuration

Each endpoint is a few lines of YAML: the URL, how often to check, and conditions such as status equals 200 and response time under 300 milliseconds. Gatus runs the checks, keeps a history, draws the status page and sends alerts to Telegram, Slack, Discord, email, ntfy and many others when a condition fails.

Because the whole setup is a file, it fits in git and gets reviewed like code. It suits people who prefer configuration they can version over clicking through a dashboard, and teams that want a public status page without a subscription.

## What running it involves

It is a single Go binary or container with a small footprint. By default it keeps results in memory, so configure SQLite or PostgreSQL storage if you want history to survive a restart. Back up the config file and the database.

A status page is meant to be seen, which may mean exposing it. Publish only the page you need, through a tunnel or reverse proxy, and remember that a public page shows the names of your services. Run it on a different machine from the ones it watches if you want it to notice them going down.

## Reach for it when

- you want monitors and a status page described in a version controlled file
- you need checks on response time and content, not only up or down
- you want alerts to many channels without a subscription

## Watch out for

- there is no interface to add monitors, every change is a YAML edit
- history is lost on restart unless you configure persistent storage
- a monitor on the same host as your services cannot report that host's outage
