## Introduction

GitNexus is an innovative client-side knowledge graph creator designed to bring deep code intelligence directly to your browser. It allows you to drop in a GitHub repository URL or a ZIP file, and instantly generates an interactive knowledge graph of your codebase. At its core, GitNexus integrates a powerful Graph RAG Agent, making it an indispensable tool for code exploration and significantly improving the reliability of AI agents working with code.

This engine operates entirely without a server for its core functionality, emphasizing privacy and local processing. It's built on a multi-phase indexing pipeline that understands your code's structure, parses its components, resolves dependencies, clusters related symbols, traces execution flows, and builds robust search indexes.

## Why Use GitNexus and Key Benefits

The true power of GitNexus lies in its "Precomputed Relational Intelligence." Traditional Graph RAG often requires AI models to perform multiple queries to understand code relationships, leading to inefficiencies and potential missed context. GitNexus addresses this by precomputing critical structural information, such as clustering, tracing, and scoring, at index time. This approach offers several key benefits:

*   **Reliability**: AI agents receive complete, pre-structured context in a single call, drastically reducing the chance of missing dependencies or breaking changes.
*   **Token Efficiency**: Eliminates the need for lengthy, multi-query chains, saving valuable token budget for LLMs.
*   **Model Democratization**: Even smaller LLMs can achieve full architectural clarity, as GitNexus handles the heavy lifting of understanding the codebase structure.

GitNexus offers two primary ways to interact with your code intelligence:

1.  **CLI + MCP (Model Context Protocol)**: Recommended for daily development, this mode indexes full repositories locally and connects directly to AI agents like Cursor, Claude Code, and Codex. It provides a persistent, fast experience using LadybugDB native bindings and Tree-sitter native parsers.
2.  **Web UI**: A browser-based visual graph explorer and AI chat. It's ideal for quick exploration, demos, and one-off analysis, running entirely in WebAssembly. Your code never leaves your machine in this mode.

For enhanced flexibility, GitNexus supports a "Bridge mode" where the Web UI can auto-detect and connect to a local `gitnexus serve` backend, allowing it to browse all your CLI-indexed repositories without re-uploading or re-indexing. GitNexus supports a wide array of languages, including TypeScript, JavaScript, Python, Java, Kotlin, C#, Go, Rust, PHP, Ruby, Swift, C, C++, Dart, and Zig, with comprehensive features like import resolution, heritage tracking, and constructor inference.

## Installation

Getting started with GitNexus is straightforward. For the CLI, you can quickly index your repository and set up your AI agents:

bash
# 1. Index your repo (run from repo root)
npx gitnexus analyze

# 2. Connect your editors (one-time, auto-detects Claude Code, Cursor, Codex, …)
npx gitnexus setup


The `analyze` command indexes the codebase, installs agent skills, registers hooks for tools like Claude Code, and creates context files. The `setup` command configures the MCP so your AI agent can leverage the generated knowledge graph. For the Web UI, no installation is required, simply visit the official link.

## Examples

GitNexus provides a rich set of MCP tools to interact with your codebase. Here are a couple of examples demonstrating its capabilities:

### Impact Analysis

Understand the blast radius of changes with high confidence:


impact({target: "UserService", direction: "upstream", minConfidence: 0.8})

TARGET: Class UserService (src/services/user.ts)

UPSTREAM (what depends on this):
  Depth 1 (WILL BREAK):
    handleLogin [CALLS 90%] -> src/api/auth.ts:45
    handleRegister [CALLS 90%] -> src/api/auth.ts:78
    UserController [CALLS 85%] -> src/controllers/user.ts:12
  Depth 2 (LIKELY AFFECTED):
    authRouter [IMPORTS] -> src/routes/auth.ts


### Process-Grouped Search

Perform intelligent searches that group results by execution processes:


query({search_query: "authentication middleware"})

processes:
  - summary: "LoginFlow"
    priority: 0.042
    symbol_count: 4
    process_type: cross_community
    step_count: 7

process_symbols:
  - name: validateUser
    type: Function
    filePath: src/auth/validate.ts
    process_id: proc_login
    step_index: 2

definitions:
  - name: AuthConfig
    type: Interface
    filePath: src/types/auth.ts
