Docker Desktop
- The simplest way to run containers on any desktop
- Compose makes multi-part apps simple
- Free for personal use and small businesses

- Firms with 250+ staff or $10M+ revenue have to pay
Docker Desktop is the easiest way to run containers on your computer. A container packs an app with everything it needs. You get the Docker engine, Compose, a local Kubernetes cluster and a friendly dashboard. It now adds sandboxes for AI coding agents, an MCP Toolkit and the Gordon AI assistant. The downsides? It eats memory and battery, and bigger companies must pay. Most backend developers still need it.
