# What is WrenAI built with?

WrenAI is a Rust repo built with Tokio. It stores its data in datafusion and pyarrow, reaches it with sqlglot, signs people in with cryptography and pyjwt, uses AI through pydantic-ai, LangChain, and LangGraph, makes its content with lxml, csv, and parquet, validates its data with Pydantic, deploys with loguru, log, env_logger, and boto3, and uses DuckDB, object_store, opendal, and arrow. It has 105,033 written lines, with 155 test files.
