Hawkeye – local code search for MS/Linux, fast 500k+ file codebase

Hawkeye is a fast local code search tool for macOS and Linux, designed for developers working with massive codebases of 500,000+ files where traditional tools like grep and IDE search become unusably slow. It eliminates the productivity-killing delays of "find all references" that break developer focus, and is especially critical for AI coding agents that waste more time re-grepping files than writing code. The project is interesting because it solves a real scaling pain point for large monorepos, enabling instant, context-preserving search that keeps both human and AI developers in flow.
