Eulix

Eulix is a local code intelligence tool that parses repositories into queryable indexes and routes questions to the cheapest mechanism.

Eulix parses your repository into a queryable index containing symbols, call graphs, and optional embeddings. It routes every question to the cheapest mechanism that can answer it, using an LLM only where reasoning is genuinely required. The tool runs locally on your machine, handling parsing, indexing, retrieval, and embedding entirely on-device without requiring a cloud account or API key. It supports multiple languages including C, C++, Go, Java, JavaScript, Python, Rust, and TypeScript. Developers can interact with it via the CLI, an MCP server for coding agents, a beta LSP server for editors, a browser-based call-graph explorer, or the standalone Rust library.
