Inspiration

Inspiration Large codebases become hard to understand, risky to modify, and slow to refactor. We wanted a developer-first tool that turns messy repositories into clear, visual structures and allows safe changes through simple natural-language commands instead of manual file hunting.

What it does The platform visualizes an entire repository as interactive dependency graphs and provides an AI-powered command terminal for refactoring, navigation, and analysis. Developers can issue natural-language instructions and instantly see structural changes reflected in real time, reducing guesswork and preventing breakages.

How we built it

  • Frontend: Next.js with ReactFlow for dynamic graph rendering and smooth interactions
  • Backend: NestJS with Prisma and BullMQ for job processing and scalable task queues
  • AI Layer: Gemini 2.5 Flash for code understanding, suggestions, and automated modifications
  • Architecture focused on modular parsing, async processing, and visual state streaming

Challenges we ran into

  • Maintaining real-time visual accuracy while processing large repositories
  • Handling multiple file types and edge-case syntax structures
  • API rate limits and batching strategies for AI requests
  • Synchronizing graph state with backend refactor operations without UI lag

Accomplishments that we’re proud of

  • A fully functional natural-language AI terminal for repository actions
  • Clean, industrial-style UI optimized for large graphs
  • End-to-end automated refactoring pipeline with visual confirmation
  • Stable performance on medium-to-large repositories

What’s next

  • WebSocket-based live updates
  • Collaborative multi-user editing
  • Automated pull-request generation
  • Multi-language parsing engines
  • Direct GitHub and GitLab integrations
  • Smarter risk analysis and rollback previews
