## What it is
Tugtainer is a self-hosted web application for automating Docker container image updates, with a web UI, per-container configuration, and multi-host support via agents. It is written in Python with an Angular frontend and distributed as a Docker image.

## Use cases
- automatically update docker containers when new images are released
- watchtower alternative with a web dashboard
- monitor container image updates across multiple docker hosts
- schedule container update checks with crontab
- get notified when containers are outdated
- manage and inspect containers from a self-hosted ui
- auto-update homelab docker services

## When to choose
- you run a homelab or self-hosted stack and want automated container updates with a UI
- you need per-container control over check-only vs auto-update behavior
- you manage containers across multiple hosts or private registries
- you want notifications about outdated images via many services

## When to avoid
- you need battle-tested tooling for production clusters - the project explicitly warns against production use
- you use Kubernetes or non-Docker runtimes
- you prefer declarative GitOps-style updates rather than a web UI

## Facets
- artifact type: application
- maturity: active
