GitNexus
GitNexus indexes a codebase into a knowledge graph of symbols, calls, dependencies
and execution flows. Use it through your coding agent's MCP tools, the CLI, or a
web graph explorer.

Quick start
Requires Node.js 22.18+ on 22.x, or 24.11+. See platform requirements
for Linux and Windows native dependencies.
# Run from your repository root
npx gitnexus analyze
# Connect your editors once
npx gitnexus setup
analyze builds the index, installs agent skills, registers Claude Code hooks,
and writes AGENTS.md / CLAUDE.md context files. setup configures MCP for your
editors. Use gitnexus analyze --index-only to index without those repository
integration files.
For repeated use, install globally with npm install -g gitnexus.
If installation fails, see troubleshooting.
What you can do
| Task | Tool |
|---|
| Find code and related execution flows | query |
| Inspect a symbol's callers and dependencies | context |
| Check what a change could affect | impact |
| Trace a path between two symbols | trace |
| Review the impact of a Git diff | detect_changes |
| Preview and apply a semantic rename | rename |
Ask your agent questions such as “What calls this function?” or “What would this
change affect?” Resolution depends on language support and available evidence;
check reported ambiguity, index freshness and coverage limits.
Editor setup
gitnexus setup detects Claude Code, Cursor, Codex, Antigravity, Factory Droid,
OpenCode, CodeBuddy and Qoder. Windsurf requires manual MCP configuration.
To select editors:
gitnexus setup -c cursor,codex
See editor setup for the support matrix, manual MCP
configuration, hooks and plugin installation.
Everyday commands
gitnexus analyze # Refresh the current repository's index
gitnexus analyze --watch # Reindex as local files change
gitnexus query "authentication" # Search the graph
gitnexus impact UserService --direction upstream
gitnexus status # Check index freshness
gitnexus list # List indexed repositories
gitnexus serve # Serve indexed repositories to the web UI
For multiple concurrent agents, use one gitnexus mcp --http --port 3111 server
and connect clients to http://127.0.0.1:3111/mcp. See the
shared-server instructions.
Web UI
Run gitnexus serve, then open gitnexus.vercel.app.
The UI connects to the backend to browse indexed repositories and use AI chat.
It uses the existing index; no re-upload or re-index is needed.
For Docker, hosted deployments, image verification, or a local frontend, see
deployment.
Supported languages
C, C++, C#, COBOL, Dart, Go, Java, JavaScript, Kotlin, Objective-C, PHP, Python,
Ruby, Rust, Swift, TypeScript, Vue and Zig have registered providers. Support
varies by construct; see the language inventories
for measured behavior, exclusions and remaining gaps.
Documentation
Security and privacy
The CLI indexes code locally without an LLM. Optional remote embeddings, wiki
generation and AI chat use the providers you configure. The web UI accesses the
backend it connects to. Review security guidance and
deployment authentication before exposing
an index to other users.
Development
See CONTRIBUTING.md for setup and pull requests,
TESTING.md for validation, and GUARDRAILS.md for
repository rules.
Enterprise
GitNexus is available as an enterprise offering — fully managed SaaS or self-hosted deployment. Commercial use of the OSS version is also available with proper licensing.
Enterprise includes:
- PR Review — automated blast radius analysis on pull requests
- Auto-updating Code Wiki — always up-to-date documentation (Code Wiki is also available in OSS)
- Auto-reindexing — knowledge graph stays fresh automatically
- Multi-repo support — unified graph across repositories
- OCaml support — additional language coverage
- Priority feature/language support — request new languages or features
Upcoming: auto regression forensics · end-to-end test generation
