## What it is
Play with Docker (PWD) is a web application that provides free Alpine Linux VMs in the browser where users can build and run Docker containers and create Swarm Mode clusters, powered by Docker-in-Docker (DIND). It is the software behind play-with-docker.com and can be self-hosted for training and labs.

## Use cases
- try docker in a browser without installing anything
- run a docker playground for workshops and training
- experiment with docker swarm mode clusters
- self-host a container sandbox for students
- spin up temporary docker environments for demos

## When to choose
- you want to give learners hands-on Docker experience with zero local setup
- you need ephemeral multi-node Docker/Swarm environments for demos or labs
- you want to self-host a container playground for your organization

## When to avoid
- you need a long-lived or production container environment - sessions are limited to 5 instances and 4 hours
- you need Kubernetes playgrounds - the hosted service is deprecated as of March 2026
- you require persistent storage or custom DIND images outside the franela/dind family
