	GitNexus A	Hex A	Figma AI A
Tagline	An open-source, MCP-native knowledge graph engine that gives AI coding agents (Cursor, Claude Code, Windsurf) genuine structural awareness of your codebase before they touch a single line.	Modern data notebook with Magic AI assistant.	AI features baked into the design tool you already use.
Category	Coding	Data	Design
Pricing	Free (MIT open source)	Free + $28+/user/mo	Included with Figma plans
Best for	Developers working in large or unfamiliar codebases who want their AI coding agent to stop making confident, structurally blind edits — especially Claude Code power users.	Data teams at startups + enterprises.	Designers already on Figma.
Strengths	Pre-computes a full dependency graph (functions, imports, class inheritance, execution flows) via Tree-sitter ASTs — agents query structure, they don't guess at it Zero-server, privacy-first: CLI runs entirely locally with no network calls; browser UI processes code client-side and never uploads it Deepest Claude Code integration on the market: MCP tools + agent skills + PreToolUse/PostToolUse hooks that auto-enrich searches and auto-reindex after commits One global MCP server handles multiple indexed repos — set up once with npx gitnexus setup and forget it detect_impact and generate_map MCP prompts give pre-commit blast-radius analysis and auto-generated Mermaid architecture docs	SQL + Python + no-code in one notebook Magic AI writes queries + viz for you Team-grade collaboration	First drafts with Make Designs Rename/rearrange layers automatically Natural language asset search
Weaknesses	Browser-side RAG has hard ceilings: WASM heap limits constrain embedding model quality compared to server-side tools; monorepos or repos >50k files hit practical walls Community-built and not officially maintained — velocity and long-term support depend on contributor goodwill Claude Code gets the full integration experience; other editors (Windsurf, Cursor) get progressively less — value is uneven depending on your editor	Overkill for casual users Enterprise pricing	Features vary by plan + region Still rolling out
Kai's verdict	GitNexus solves a real and underappreciated problem: AI coding agents are syntactically fluent but architecturally blind, and plugging a pre-computed knowledge graph into the MCP layer is the right fix. 28k GitHub stars in days suggests the pain is widely felt — just go in knowing it's a community project, not a polished product. (Verdict pending Phi's full review.)	A-tier for data teams. S-tier if you already live in SQL + Python.	A-tier. No reason not to use it if you're on Figma. Not worth switching for.
