Harbor internal AI prototyping tool
Stripe employees created 12,000 prototypes with its internal Harbor AI tool
Problem
Designers needed to test interactive ideas without committing engineering time to a full prototype.
Approach
Stripe built Harbor as a browser-based AI prototyping tool using its design systems. Employees described an idea, and an agent wrote code and inspected the rendered result. Published prototypes could be shared for review, and teams outside design adopted the tool for internal work.
Results
Takeaway
Harbor's adoption extended beyond its original design use. Prototype counts measured use rather than verified time savings.
