## What it is
Pyrra is an open-source tool for defining, managing, and visualizing Service Level Objectives (SLOs) with Prometheus. It generates Prometheus recording rules and multi burn rate alerts from YAML SLO definitions and provides a UI and Grafana dashboards for tracking error budgets.

## Use cases
- define and manage SLOs for services monitored by Prometheus
- generate multi burn rate alerts from SLO targets
- visualize error budgets and burn rates in a web UI
- create Grafana dashboards for SLO tracking
- run SLO management as a Kubernetes operator
- track availability and RED metrics for services

## When to choose
- you use Prometheus (or Thanos) and want automated SLO recording rules and burn rate alerting
- you want a ready-made UI and Grafana dashboards for error budgets
- you run Kubernetes and want SLOs managed via an operator

## When to avoid
- you don't use Prometheus-compatible metrics backends
- you need SLO management for non-metrics data sources like logs or traces
- you prefer building custom SLO tooling with your own alerting logic
