reflex-search/reflex

What it does

Reflex is a local fulltext code search tool designed specifically for AI coding agents. It enables fast, offline code searching across large codebases using trigram indexing technology to deliver sub-100ms query responses. The tool supports 18 programming languages and operates entirely locally without requiring cloud services.

How to set up

Reflex is available as an MCP (Model Context Protocol) server. Installation involves cloning the reflexsearch/reflex repository from GitHub and running it as a local service. Configuration is minimal as it's designed to work offline with your existing codebase. Detailed setup instructions are available in the GitHub repository.
