# What is LangBot built with?

LangBot is a Python repo built with quart, AIOHTTP, React, react-router-dom, and Vite. It stores its data in Postgres and chromadb, reaches it with sqlmodel, SQLAlchemy, and alembic, signs people in with argon2-cffi, cryptography, pyjwt, and @simplewebauthn/browser, uses AI through LangChain, langsmith, Ollama, tavily-python, tiktoken, and 4 more, makes its content with ebooklib, html2text, mako, pypdf, python-docx, and 14 more, validates its data with Pydantic, @hookform/resolvers, and Zod, is tested with Pytest, pytest-asyncio, and @playwright/test, deploys with boto3, botocore, colorlog, and psutil, and uses aiosqlite, async-lru, asyncpg, pgvector, pymilvus, and 2 more. It has 640,677 written lines, with 850 test files.
