Strengths and weaknesses
Docker Desktop
- Easiest way to run containers on any desktop
- Compose makes multi-service apps simple
- Free for personal use and small businesses
- Heavy on memory, CPU and battery
- Larger companies must pay per user
Docker Desktop is the easiest way to run containers on your own machine. It bundles the Docker engine, Compose, a local Kubernetes cluster and a friendly dashboard, and it can now run AI models and MCP tools locally too. The downsides: it uses a lot of memory and battery, especially on laptops, and larger companies need a paid subscription. Still essential for most backend and full-stack developers.

Postman
- Covers the whole API lifecycle in one tool
- Easy to share collections with teammates
- Strong support for many API protocols
- Desktop app is heavy and can feel slow
- Most work is stored in Postman's cloud
Postman is the most complete tool for working with APIs. You can send requests, organize them into collections, write tests, generate docs, run mock servers and monitor endpoints, with support for REST, GraphQL, gRPC and WebSockets. Teams get shared workspaces and version control. The downsides are a heavy desktop app, constant nudges toward paid plans, and a push to store your work in Postman's cloud.
