Active·★ 57·MIT·Updated 2026-10-14
Srclight builds a rich, searchable index of your codebase that AI coding agents can query instantly, replacing inefficient grep/glob calls with precise, structured lookups. It provides comprehensive code intelligence, including symbol search, relationship graphs, and semantic search, all while operating fully local and private.

Use cases
↳AI agents can instantly get codebase overviews and find callers/callees, drastically reducing orientation time.
↳Developers can perform semantic searches with natural language queries like "find code that handles authentication" to locate relevant code by meaning.
↳Before committing changes, analyze the "blast radius" to see what other parts of the codebase will be affected, preventing unintended breaks.
↳Integrate with MCP clients like Claude Code or Cursor to enhance AI's ability to understand, navigate, and modify complex codebases.
↳Index and search across multiple projects simultaneously, providing a unified code intelligence view for large codebases or monorepos.
