Choose Maritime if

Development teams that want a shared, full-featured workspace for testing, mocking and documenting APIs.
- Industry standard; many API vendors ship ready Postman collections
- Testing, mocking, docs and monitoring in a single tool
- Capable Free plan for solo developers
Look elsewhere if: Developers who want a lightweight Git-native client or just a docs portal (Bruno, Insomnia, ReadMe, Scalar).
