Essential Utilities to Boost Producitivity

demongrep – fast, local semantic code search

Search your codebase using natural language queries like “where do we handle authentication?” — all running locally with no API calls.

This is free and open source software.

Features include:

  • Semantic Search — Natural language queries that understand code meaning.
  • Hybrid Search — Combines vector similarity + BM25 full-text search with RRF fusion.
  • Neural Reranking — Optional second-pass reranking with Jina Reranker for higher accuracy.
  • Smart Chunking — Tree-sitter AST-aware chunking that preserves functions, classes, methods.
  • Context Windows — Shows surrounding code (3 lines before/after) for better understanding.
  • Local & Private — All processing happens locally using ONNX models, no data leaves your machine.
  • Fast — Sub-second search after initial model load, incremental indexing.
  • Multiple Interfaces — CLI, HTTP server, and MCP server for Claude Code integration.
