Why Reflex

Fast at Scale

Indexes a 27,448-file Kubernetes checkout in 7.7s on 16 cores. Median queries on a 30 MB corpus: ~3ms for a common word, ~12ms for a regex.

Complete Coverage

Finds every occurrence — not just definitions — across the same files ripgrep searches. Whole-identifier matching by default, plus substring and case-insensitive search.

AI-Native

MCP server with 17 tools, JSON output for agent pipelines, built-in AI query assistant. In A/B tests, same task success at ~31% lower cost per task.

15 Languages + Text

Rust, TypeScript, Python, Go, Java, C/C++, and more, parsed with Tree-sitter for precise symbols. Every other non-binary file is indexed for full-text search.

Dependency Analysis

Import tracking, reverse lookups, circular detection, hotspot analysis across your entire codebase.

Deterministic

Fully local, fully offline. Same query, same results, and every response says whether the index is fresh. Your code stays on your machine.
