Why Reflex

Sub-100ms Queries

Trigram indexing with memory-mapped I/O. 2–3ms on small codebases, under 250ms on the Linux kernel.

Complete Coverage

Finds every occurrence — not just definitions. Same query always produces the same results.

AI-Native

MCP server with 15 tools, JSON output for agent pipelines, built-in AI query assistant.

15 Languages

Rust, TypeScript, Python, Go, Java, C/C++, and more. Tree-sitter parsing for precise symbol extraction.

Dependency Analysis

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

Deterministic

Fully local, fully offline. No cloud, no non-determinism. Your code stays on your machine.
