GRASP - Code Architecture Visualizer: See any codebase's architecture in seconds

Hi Product Hunt 👋

Every time I joined a new codebase, or reviewed a PR that touched code I didn't know, I lost the first hours just working out how the pieces fit together. So I built Grasp.

Paste a GitHub or GitLab URL (cloud or self-hosted), or open a local folder, and in seconds you get:

🕸️ A live dependency graph of every file and import, plus 9 other views (architecture by layer, treemap, matrix, flow, bundle, 3D, heatmap…)

🩺 A health score, technical-debt estimate, circular dependencies, complexity hotspots and vulnerable dependencies (OSV.dev)

🤖 150 MCP tools, so Claude Code, Cursor, Copilot or any MCP agent can ask "what breaks if I change this file?" without reading the whole repo

🧭 Onboarding reading paths, migration plans, SBOM/SARIF output and a team dashboard across repos

🔒 It runs in your browser: no install, no account, no telemetry. Your code never leaves your machine. AI chat is off by default and uses your own key or a local model (Ollama, LM Studio).

It's also in VS Code, JetBrains, Chrome and Safari, as a GitHub Action, a GitLab CI component and a Docker image, and for Neovim, Vim, Emacs and Zed.

Try it on Express in one click: https://ashfordeou.github.io/grasp/?repo=expressjs/express

It's free (Elastic License 2.0). I'd love to hear which repo you tried and what you wished it showed.
