## What it is
WUD (What's up Docker?) is a self-hosted service that continuously monitors Docker containers, detects newer image versions across many registries, and notifies you or triggers automatic updates. It offers a web dashboard, REST API, Prometheus metrics, and 15+ notification/action triggers.

## Use cases
- keep docker containers up to date
- get notified when a new container image version is released
- automatically update docker containers when new images are available
- monitor docker image updates across multiple registries
- track container version drift in docker compose or kubernetes
- send container update alerts to discord, telegram, or ntfy

## When to choose
- you run self-hosted Docker/Kubernetes workloads and want automated image update detection and notifications
- you need registry support beyond Docker Hub (GHCR, ECR, GCR, Quay, private OCI registries)
- you want semver/regex-based version filtering and automatic container recreation
- you want a web UI plus Prometheus metrics for container update tracking

## When to avoid
- you need full image vulnerability scanning or security patching, not just version updates
- you want a simple one-shot CLI updater rather than a continuously running service
- you don't run containers at all
