Summary
API management in 2026 is shifting from cloud-centric (Postman) toward git-native (Bruno) and browser-based (Hoppscotch) approaches. The best choice depends on your team's workflow preferences. Whichever tool you choose, ensure it connects to your CI/CD pipeline for automated testing and your PM tool (like Refront) for task tracking.
Frequently Asked Questions
Is Postman still the best API tool?
For feature completeness and team collaboration, yes. However, Bruno and Hoppscotch are compelling alternatives for teams that want open-source, git-native, or browser-based workflows.
Should API collections be stored in git?
Ideally yes. Git-stored collections (Bruno) ensure your API tests are version-controlled alongside your code. This eliminates sync issues and makes API testing part of your PR workflow.
How do API tools fit into project management?
Track API development tasks as tickets in Refront, link them to specifications and test collections, and use CI/CD integration to verify API changes automatically before deployment.
