HTTPie

HTTPie started as a CLI (http get example.com) and now includes a beautiful Desktop app (2025). It is famous for its human-friendly syntax.

When to Use

• CLI: http POST api.com name=John is faster than curl -X POST -d '{"name":"John"}' ....
• Desktop: Cleanest UI in the business. AI-assisted request building.
• Quick Testing: Zero config needed.
