Postman vs Bruno 2026: API Client Comparison
Postman vs Bruno 2026: cloud-first vs git-first API clients, scripting, collaboration, CLI testing.
Postman
Most-installed API client + collaboration platform
- License
- Proprietary
Bruno
Open-source git-friendly API client
- License
- MIT
Postman is the incumbent — 30M+ users, cloud-first collections, advanced collaboration. Bruno is the open-source upstart that stores collections as plain text .bru files in git. The Bruno wave in 2026 is partly a reaction to Postman moving features behind paid Cloud (scratch pad removal, free tier limits). For teams that want collections in git, Bruno is winning hearts. For full-featured API workflows + collaboration, Postman remains king.
