Lanarky

Lanarky is an open-source framework to deploy LLM applications in production. It is built on top of FastAPI and comes with batteries included.

• supports LangChain
• simple gradio chatbot UI for fast prototyping

See Roadmap for upcoming features.

There are great low-code/no-code solutions in the open source to deploy your LLM projects. However, most of them are opinionated in terms of cloud or deployment code. This project aims to provide users with a cloud-agnostic and deployment-agnostic solution which can be easily integrated into existing backend infrastructures.

The library is available on PyPI and can be installed via pip.

pip install lanarky
