Bloop

Bloop is an AI-powered code search and assistant tool that allows developers to ask questions about their codebase in natural language. It uses semantic search to find relevant code, functions, and files, even without exact keyword matches. Written in Rust, it's fast and can be run locally or self-hosted, ensuring code privacy. Its recent integration of LLMs allows it to generate answers and explanations based on search results.

It targets developers working with large, unfamiliar, or legacy codebases who need to quickly understand and navigate code. It ranks for its strong focus on privacy, effective semantic search, and utility as a discovery and comprehension tool.
