What is Cruss?
Cruss is a collaborative API development workspace where engineering teams build, test, document and share APIs together. A workspace is your team’s central place to design and organise requests, run collection suites, generate documentation, and keep everyone aligned — from local development through production.
💡
Cruss is a collaborative workspace, not a solo tool. It excels at team API development: shared collections, automated collection runs, request chaining, and documentation that writes itself.
