Popular vibe coding tools like Cursor, Claude Code, or Windsurf are powerful — but they don't fully
Popular vibe coding tools like Cursor, Claude Code, or Windsurf are powerful — but they don't fully know your codebase structure. When you edit a file, the AI often ignores 47 functions that depend on its return type.
This greatly affects the output and could introduce breaking codes or vulnerabilities to your project.
GitNexus is trying to solve this issue.
GitNexus builds a complete knowledge graph of your codebase through a multi-phase indexing pipeline:
Structure:
Shows the file tree and maps folder/file relationships
Parsing:
Extracts functions, classes, methods, and interfaces using Tree-sitter ASTs
Resolution:
Resolves imports and function calls across files with language-aware logic
Clustering:
Groups related symbols into functional communities
Processes:
Traces execution flows from entry points through call chains
Search:
Builds hybrid search indexes for fast retrieval
There are two ways to run this app:
: Everything runs locally on your machine. No network calls.
: Everything runs in your browser. No code uploaded to any server. API keys are stored in localStorage only.
Let's get into the details.
Web UI
Head over to GitNexus's web app and add your project source code. You can upload either a zip file or a GitHub repository.

The app clones the repo and shows a beautiful knowledge graph of every file, dependency, call chain, cluster, and execution flow.

You can select a node from the graph or manually choose a file/function from the graph to visualize other files or functions related to it.
This gives you a deep architectural view of your codebase so you stop missing dependencies, breaking call chains, and shipping blind edits.
Another interesting feature of this app is the built-in AI-powered chat app. You can toggle it via the Nexus AI button on the upper right.

You can set the provider and add your own API key in the settings page:

The web UI uses the same indexing pipeline as the CLI but runs entirely in WebAssembly.
You can also run this app locally by simply running this command:
CLI + MCP
This is the recommended way to run GitNexus.
The CLI indexes your repository and runs an MCP server that gives AI agents deep codebase awareness.
You can get started by running this command:
This indexes the codebase, installs agent skills, registers Claude Code hooks, and creates all necessary context files.
Here are the CLI commands you can use:
You can even generate LLM-powered documentation from your knowledge graph!
The wiki generator reads the indexed graph structure, groups files into modules via LLM, generates per-module documentation pages, and creates an overview page — all with cross-references to the knowledge graph.
Alright, that's it...
The Web UI looks cool, but there's not much you can do with it aside from visually exploring your repo. But the more interesting feature is the CLI+MCP. This gives vibe coding tools more context and awareness of your entire codebase, which reduces the risk of broken code or a fractured codebase.
The automated documentation generation is also a nice-to-have feature. This saves you a bunch of time creating a base version of your technical documentation.
