Opyrator, which is only recommended for experimental usage, leverages FastAPI, Streamlit, and Pydantic to enable users to convert Python functions into production-ready microservices that can be deployed (locally or via Docker) and accessed by HTTP API or an interactive UI. Functions must have an input parameter and return value based on Pydantic models. Opyrator can power use cases ranging from text preprocessing to image super-resolution to audio separation.
