The all-seeing eye of a codebase
Polaris
"If I touch this, what breaks?"
Every engineer knows the fear. You change one small function, you push, and three repos away a component falls over. Polaris ends that fear.
- Reads every function, call, and path across several product repos, and keeps the whole call graph in MongoDB.
- Walks callers of callers to give a risk score and the full blast radius, before you light the fuse.
- Sees across the wall: it follows HTTP calls from a Go backend to the exact React components that depend on them, about 315 bridges in its first home.
- Speaks the product's language: "this change touches billing, auth, and video generation."
- One link opens a live graph of every touched node. Agents ask it questions over MCP, HTTP, or CLI.
