Overview
osgrep is a local semantic code search tool that works like grep but accepts natural-language questions. It is built for coding agents, helping them find relevant code with fewer tokens. Embeddings run locally through onnxruntime-node, and each repository gets its own index that is created on the first search. You install it with npm and search from inside a repo.
Key features
- Finds concepts such as where authentication is handled
- Call graph tracing with the trace command
- Labels code roles such as orchestration and definition
- Fully local embeddings, with a separate index per repository
- Output includes symbols, roles and call graphs for agents
Best for
Developers and coding agents that need to find code by meaning in a repository. Embedding models of about 150MB are downloaded during setup or on first use.
