01
Analyze your src
Point the CLI at your React/TypeScript tree. Arclens walks the AST and classifies nodes.
Product
From files to architecture
Without running the app.
Arclens uses static AST analysis to map your entire React and TypeScript project in seconds — rendering an interactive node-graph without requiring a dev server or build step.
✓
Zero-Runtime Parsing
Parses JSX, hooks, context, and import graphs safely without executing untrusted code.
✓
Interactive Neighborhood Focus
Isolate any component or utility and examine upstream/downstream dependents instantly.
✓
100% Local & Private
Your codebase never leaves your filesystem. No external uploads or cloud dependencies.
How it works
Run a command. Get a graph.
No config files, no build step, no runtime required.
02
Get a graph + insights
Dependencies become edges. The terminal prints orphans, naming hints, and Hooks rule checks.
03
Explore in the viewer
Search nodes, focus neighborhoods, and trace what will move if you change a file.
Free tier
Built for your day job and side projects.
Most React apps are small enough to map locally. Install Arclens, run analyze, and explore the graph without signing up or hitting a paywall on day one. Pro is there when the repo gets big enough that you feel the limits, not before.
LOCAL-FIRST
100% Private & Local
Analyze codebases entirely on your local machine. Zero code telemetry, remote uploads, or mandatory account signups required.
CORE EXPLORER
Full Interactive Graph
Detect components, hooks, contexts, and imports with interactive search, cluster grouping, and neighborhood focus capabilities out of the box.
HONEST LIMITS
Generous Soft Limits
Built to handle full side projects and production codebases effortlessly. Best-effort execution without artificial functional paywalls.
GROWTH-READY
Upgrade When You Scale
Pro is ready when your repository requires team CI checks, Next.js architecture depth, or monorepo impact analysis.
