You don’t need one specific type — both GUI and CLI tools can be used for API testing. The better choice depends on your workflow.
Choose a GUI tool if you want:
- An easy visual interface
- Quick manual testing
- Team collaboration and sharing collections
- Less command-line setup
Examples: Postman, Insomnia, Swagger UI
Choose a CLI tool if you want:
- Automation and scripting
- Integration with CI/CD pipelines
- Repeatable tests in terminal environments
- Version-controllable test scripts
Examples: curl, httpie, newman, pytest + requests
Practical recommendation
- For manual exploration: use a GUI tool
- For automated testing: use a CLI tool
- Many teams use both: GUI for development/debugging, CLI for regression tests and CI
If you tell me whether you’re testing manually, automating, or working in CI, I can recommend the best option.
