Add this badge to your README to show your security score and help users find safe servers.
Turn any repo into a queryable graph of nodes and typed edges — each with AI technical, business, and security summaries — and use it from your CLI, your AI agent (MCP + Skill), or an interactive web UI. Runs entirely on your machine.
Run this in your terminal to verify the server starts. Then let us know if it worked — your result helps other developers.
npx -y '@devlensio/skill' 2>&1 | head -1 && echo "✓ Server started successfully"
After testing, let us know if it worked:

Intelligent codebase visualizer.
Turn any JavaScript, TypeScript, React, Next.js, or Node.js repo into a living, queryable map — with functional summaries, technical summaries, and security analysis on every node.

DevLens is a codebase visualizer for JavaScript, TypeScript, React, Next.js, and Node.js projects. It builds a typed dependency graph of every component, hook, function, route, and store — with AI-powered summaries on each node — so you can explore, understand, and analyze your architecture in seconds instead of hours.
What makes it different? Instead of reading files one at a time, you (or your AI agent) query the pre-built graph. A node summary costs ~50 tokens vs ~2,000 tokens per file.
Your agent burns tokens re-reading files it's seen before. DevLens gives it a graph to query instead.
Coming soon — DevLens Cloud: Shareable graphs your whole team can access, cross-repo navigation, and giving graphical context to your AI agents for smarter code review and analysis — all without running anything locally.
1. Install
npm install -g @devlensio/cli
No Node.js? Use the standalone binary installer (no dependencies):
Linux / macOS:
curl -fsSL https://raw.githubusercontent.com/devlensio/devlensOSS/main/scripts/install.sh | shWindows (PowerShell):
irm https://raw.githubusercontent.com/devlensio/devlensOSS/main/scripts/install.ps1 | iex
2. Init
cd your-project
devlens init
This sets up your LLM provider for AI summaries. Don't need AI? Skip this — structural analysis works offline.
3. Analyze
devlens analyze . --summarize
This builds a typed dependency graph
