## What it is
pint is a Prometheus rule linter and validator written in Go by Cloudflare. It checks alerting and recording rules for problems, either offline or by querying a live Prometheus server, and runs in CI, ad-hoc, or daemon modes.

## Use cases
- lint prometheus alerting rules in CI
- validate prometheus recording rules before merge
- check promql rules against a live prometheus server
- run a daemon that continuously validates rule files and exposes metrics
- find bugs in prometheus rule files offline

## When to choose
- you manage Prometheus alerting or recording rules and want automated validation
- you want to catch bad PromQL queries and rule mistakes in pull requests
- you need continuous rule checking with metrics output

## When to avoid
- you use Thanos or other partially compatible services instead of real Prometheus
- you need a linter for non-Prometheus monitoring systems
