About
We built the tool we always needed on day one.
Vast is an AI-powered code architecture visualizer. It turns GitHub repositories and infrastructure files into interactive dependency graphs - so engineers can understand complex systems in minutes, not weeks.
We started Vast because onboarding into a new codebase shouldn't feel like archaeology. You shouldn't need to spend two weeks reading files and asking questions just to understand how 47 services talk to each other. That information exists - it's just buried.
Vast surfaces it automatically.
What we do
You connect a GitHub repository or upload a YAML file. Vast analyzes the structure, builds a dependency graph, and highlights the things that matter: circular dependencies, overloaded services, isolated modules, deep chains. No manual diagramming. No stale documentation. Just the real picture of your system, generated in under 60 seconds.
Where we're going
v1 is 2D graphs with automatic diagnostics. v2 brings an AI assistant that explains architectural problems and suggests fixes. v3 adds full 3D visualization and team collaboration.
We're building this in public, shipping fast, and listening closely to the engineers who use it.
If you have feedback, a feature request, or just want to say the tool helped you - we'd genuinely love to hear it.
