What is CodeNexus?

CodeNexus is a local-first context engine that helps AI coding agents understand your codebase better. It builds a live dependency graph of your code and serves only the relevant context to AI agents, reducing token usage by 50-70% while improving code quality.

Key Features

• Local-first: Your code never leaves your machine
• Token reduction: Save 50-70% on AI API costs
• Multi-language: Python, JavaScript, TypeScript support
• MCP compatible: Works with Claude Code, Cursor, and other AI agents
• Fast indexing: SQLite-based dependency graph

Basic Usage

# Index your project
codenexus index

# Search for context

Roadmap

• Tree-sitter integration for better parsing
• Graph centrality (PageRank) for better ranking
• Local LLM support for additional savings
• Multi-repo workspace support
• VS Code extension
