We built a tool that instruments a frontend repo (Angular, React, tested with auth guards and deep API coupling) so it runs entirely on mock data with zero backend dependency. Any screen in the app becomes instantly navigable.

Reshaping the data for a specific screen state takes seconds.

The instrumentation itself costs roughly $10 in LLM cost and 10-20 minutes of human navigation to finalize for a real-world repo.

Once instrumented: - Jump to any screen without setting up test data - Share a URL of the fully working frontend with no backend running - Collaborate with team through comments on specific items - Future: drive coding agents to make suggested changes
