If you want alternatives to Postman for API testing, the best choice depends on whether you want a desktop app, browser tool, CLI tool, or automated testing framework.

Good alternatives

1. Insomnia

  • Very popular Postman alternative
  • Clean UI, easy for REST, GraphQL, gRPC
  • Good for collaborative workflows
  • Great if you want a similar GUI experience

2. Hoppscotch

  • Lightweight, open-source, browser-based
  • Fast and simple
  • Good for quick API calls without installing heavy software
  • Best if you want something minimal

3. Thunder Client

  • VS Code extension
  • Great if you live in VS Code and want to keep everything in one place
  • Good for quick manual API testing

4. cURL + HTTPie

  • Command-line tools
  • Excellent for scripting and debugging
  • Best for developers who prefer terminal workflows
  • HTTPie is more user-friendly than raw cURL

5. Paw (macOS only)

  • Polished native macOS API client
  • Great UX, but limited to Apple devices
  • Good if you want a premium desktop feel

6. Bruno

  • Local-first API client
  • Uses files in your repo, which is great for version control
  • Good for teams that want API collections in Git
  • Strong choice if you want to avoid cloud sync

7. Pythons / JS testing frameworks

If you mean automated testing rather than manual request testing:

  • pytest + requests for Python
  • Jest + supertest for Node.js
  • Karate for API testing and assertions
  • RestAssured for Java

Quick recommendation

  • Closest to Postman: Insomnia
  • Lightweight browser-based: Hoppscotch
  • Best inside VS Code: Thunder Client
  • Best for Git-based workflows: Bruno
  • Best for automation: pytest, Karate, or RestAssured

If you tell me your setup (Windows/macOS/Linux, GUI vs terminal, manual vs automated testing), I can recommend the best one for you.
