If you want to test APIs with minimal coding, these are the best options:
1. Postman
- Very popular and beginner-friendly
- Great for sending requests, saving collections, and automating simple tests
- Supports environment variables, auth, and basic test scripts
2. Insomnia
- Clean, simple interface
- Good for REST, GraphQL, and gRPC
- Easier than coding, but still powerful
3. cURL
- Lightweight command-line tool
- Good if you’re comfortable in a terminal
- Less code than writing a full test suite, but not as user-friendly as GUI tools
4. Hoppscotch
- Web-based and lightweight
- Good for quick API checks without installing much
- Nice for REST and GraphQL
5. Swagger UI / OpenAPI tools
- If your API has an OpenAPI spec, you can test endpoints directly in the browser
- Useful for exploring and trying requests quickly
Best choice:
- Postman if you want the most complete no/low-code API testing tool
- Insomnia if you want a simpler, cleaner experience
- Hoppscotch if you want something fast and web-based
If you want, I can also recommend the best tool for your specific API type (REST, GraphQL, gRPC, authenticated APIs, etc.).
