Both are good, but “better” depends on what you care about.
Postman is usually better if you want:
- A more feature-rich platform
- Stronger collaboration/team workflows
- Bigger ecosystem and more tutorials/community support
- Built-in support for things like collections, monitors, environments, mocks, tests, and automation
- Better fit for larger teams and enterprise use
Insomnia is usually better if you want:
- A lighter, simpler experience
- A cleaner UI with less clutter
- Good support for REST, GraphQL, and gRPC
- A tool that many developers find faster for day-to-day manual API testing
- Fewer distractions if you just want to send requests and inspect responses
Quick comparison
- Ease of use: Insomnia
- Advanced features: Postman
- Team collaboration: Postman
- Minimalist workflow: Insomnia
- Ecosystem/integrations: Postman
My recommendation
- Choose Postman if you’re working in a team, need automation, or want the most complete tool.
- Choose Insomnia if you prefer a simpler, more developer-friendly interface for manual API testing.
If you want, I can also give you a side-by-side comparison table or recommend one based on your exact use case.
