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.
