smgrep

Semantic code search, GPU-accelerated.

Natural-language search that works like `grep`. Fast, local, GPU-accelerated, and built for coding agents.

• Semantic: Finds concepts ("where do transactions get created?"), not just strings.
• GPU-Accelerated: CUDA on NVIDIA GPUs, Metal on Apple Silicon.
• Local & Private: 100% local embeddings. No API keys required.
• Auto-Isolated: Each repository gets its own index automatically.
• On-Demand Grammars: Tree-sitter WASM grammars download automatically as needed.
• Agent-Ready: Native MCP server and Claude Code integration.

Quick Start

1. **Install**

   cargo install smgrep

   Or build from source:

   git clone https://github.com/can1357/smgrep
   cd smgrep
   cargo build --release

   For CPU-only builds (no CUDA):

   cargo build --release --no-default-features

2. **Setup (Recommended)**

   smgrep setup

   Downloads embedding models (~500MB) and tree-sitter grammars upfront. If you skip this, models download automatically on first use.

3. **Search**

   cd my-repo
   smgrep "where do we handle authentication?"

   **Your first search will automatically index the repository.** Each repository is automatically isolated with its own index. Switching between repos "just works".
