Grasp — Code Architecture

Dependency graph, health score, and security scanner for GitHub and GitLab repos

Grasp adds a single button to every GitHub and GitLab repository page. Click it and you get a full interactive architecture visualisation of any codebase in seconds, without cloning anything and without sending code anywhere. WHAT YOU GET Dependency Graph See how every file, function, class, and module connects. Choose from 9 layout algorithms (force-directed, hierarchical, radial, concentric, grid, breadthfirst, cose, dagre, elk) and 16 colour themes. Zoom, pan, filter by language or directory. Export as SVG or PNG. Health Score Every repo gets a letter grade from A to F based on modularity, complexity, dependency depth, circular imports, dead code, and churn. Assess code quality before committing to it. Security Scanner Static analysis across 34 languages. Detects hardcoded secrets, injection vulnerabilities, insecure patterns, and dependency issues. Exports findings in SARIF 2.1 format, compatible with GitHub Advanced Security and standard SAST pipelines. Blast Radius Click any file or function and see exactly what would break if it changed. Reverse dependency tracing across the full graph enables instant impact assessment. Churn Heatmap Git history overlaid on the graph. Frequently modified files surface immediately. Identifies instability and risk concentration. ORM Query Map Tracks Prisma, TypeORM, Sequelize, and SQLAlchemy query patterns across the codebase. Shows which models are accessed, from where, and at what frequency. AI Chat with 15 Providers Query any codebase in plain language. Supports Claude, GPT-4o, Gemini, Mistral, Ollama, and others. Responses are grounded in the actual graph structure. MCP INTEGRATION Grasp includes a Model Context Protocol server with 116 tools, 8 dynamic resources, and 2 guided workflow prompts. Connect Claude Code, Cursor, Windsurf, Copilot, or any MCP-compatible editor and enable direct graph querying for entry points, call chains, execution paths, change detection, and automatic AGENTS.md generation. Install the MCP server: npm install -g grasp-mcp-server PERSISTENT GRAPH DATABASE Each analysed repository is stored in a Kuzu graph database and SQLite brain store. Functions, classes, imports, and call relationships persist. Reloads are instant. Sessions persist across browser restarts. PRIVACY Zero data collection. No analytics, telemetry, or sign-up. Runs entirely in the browser using GitHub or GitLab APIs with an optional personal token. No data leaves the machine. SUPPORTED HOSTS Works with github.com and gitlab.com. Supports self-hosted GitLab, GitHub Enterprise, Gitea, and Forgejo with permission. HOW TO USE 1. Visit any GitHub or GitLab repository page 2. Click the Grasp button in the top bar 3. Explore the graph, health score, and security findings 4. Optionally add a personal access token for higher rate limits and private repositories Open source. Free forever.
