DevRag
Free Local RAG for Claude Code - Save Tokens & Time
日本語版はこちら | Japanese Version
DevRag is a lightweight RAG (Retrieval-Augmented Generation) system designed specifically for developers using Claude Code. Stop wasting tokens by reading entire documents - let vector search find exactly what you need.
Why DevRag?
When using Claude Code, reading documents with the Read tool consumes massive amounts of tokens:
- ❌ Wasting Context: Reading entire docs every time (3,000+ tokens per file)
- ❌ Poor Searchability: Claude doesn't know which file contains what
- ❌ Repetitive: Same documents read multiple times across sessions
With DevRag:
- ✅ 40x Less Tokens: Vector search retrieves only relevant chunks (~200 tokens)
- ✅ 15x Faster: Search in 100ms vs 30 seconds of reading
- ✅ Auto-Discovery: Claude Code finds documents without knowing file names
