## What it is
Promgen is a Django-based web application that generates and manages Prometheus configuration files, alert rules, and notification routing. It provides a management UI, API, and integrates with AlertManager for alert notifications.

## Use cases
- manage prometheus config files through a web ui
- generate prometheus scrape configs from service registry
- configure alert rules and notification routing for alertmanager
- self-hosted ui for managing prometheus targets and alerts
- route alertmanager notifications to different services

## When to choose
- you manage many prometheus targets and want a web UI instead of hand-editing YAML
- you need centralized alert rule and notification management across teams
- you want a self-hosted django app with plugin extensibility for discovery and notifications

## When to avoid
- you have a small single prometheus setup where plain config files suffice
- you prefer gitops-style config management rather than a database-backed UI
- you need a fully managed monitoring SaaS
