Lumen Semantic Code Search

Example Use Cases

• 1

  Perform semantic code search to find relevant code snippets efficiently.

• 2

  Reduce API costs and latency by avoiding reading entire files.

• 3

  Local, privacy-preserving code indexing without cloud dependencies.

Description

Lumen is a 100% local semantic code search engine designed for AI coding agents like Claude Code. It indexes codebases by splitting files into semantic chunks and embedding them locally using open-source models, enabling fast and cost-effective semantic search without relying on cloud services or external databases. Lumen supports multiple programming languages, incremental indexing, and Git worktree integration, significantly reducing cost, time, and output tokens while maintaining patch quality.
