Atlas Architecture Map
See how your codebase is really structured — and what will break before you change it.
Atlas indexes your project and builds an interactive architecture map: layers, folders, files, and the dependencies between them. Use it to explore impact, run what-if scenarios, and ask questions about the graph.
Works across languages — Atlas reads your source tree, not a single framework.
Features
Architecture map
- Zones: UI · API · Domain · Data · Infra
- Drill into zones and folders, expand blocks to see files
- Dependency arrows between modules (imports and calls)
- Multi-project workspaces — open a map per project or side by side
Impact analysis
- From the editor cursor or from a file on the map
- See who depends on a symbol or file, laid out as a focused impact view
What-if
- Drag a file or folder into another architectural zone
- Rewire a call edge and preview breaks and risks before you commit
Ask Graph
- Natural-language questions over the indexed graph
- Optional LLM in settings for richer answers
Service Designer
- Sketch services, groups, and port-to-port links
- Persist design next to the repo (
.atlas/design.json)
Preview
- Highlight related UI when you select files on the map
- Optional live preview URL for running apps
Getting started
- Install Atlas Core from the Extensions marketplace

Most features work with the bundled local engine out of the box. A remote engine is optional for team / hosted setups.
Privacy
Atlas analyzes code in your workspace. Local indexing stays on your machine unless you configure a remote engine.
