# What is microservices-demo built with?

microservices-demo is a Go repo built with ASP.NET Core, Gorilla, Flask, anyio, flask-cors, and 2 more. It stores its data in Postgres, reaches it with SQLAlchemy, signs people in with cryptography, flask-login, and itsdangerous, uses AI through LangGraph, langgraph-sdk, langsmith, LangChain, and langchain-google-genai, connects to Google, makes its content with filetype, markupsafe, pillow, and jinja2, validates its data with annotated-types, Pydantic, and github.com/go-playground/validator/v10, is tested with Pytest, Faker, and Locust, deploys with opentelemetry-distro, opentelemetry-instrumentation, opentelemetry-semantic-conventions, psutil, python-json-logger, and 10 more, and uses asyncpg, google-cloud-core, Npgsql, pgvector, pgx, and 5 more. It has 9,171 written lines, with 6 test files.
