The Opportunity

Problem

Development students are blocked by restrictive free tiers in API testing tools like Postman, limiting hands-on practice for learning RESTful services.

Solution

RestRelay lets dev students share API collections and workspaces in real-time for group projects. Instructors assign tests, teams collaborate without limits, and everyone sees live results. Perfect for bootcamps overcoming Postman's solo-free-tier issues.

Target Audience

Development students learning RESTful APIs and API testing

Differentiator

Real-time team collaboration tailored for classrooms, not just solo use.
