Flama is a python library which establishes a standard framework for development and deployment of APIs with special focus on machine learning (ML). The main aim of the framework is to make ridiculously simple the deployment of ML APIs, simplifying (when possible) the entire process to a single line of code.

The library builds on Starlette, and provides an easy-to-learn philosophy to speed up the building of highly performant GraphQL, REST and ML APIs. Besides, it comprises an ideal solution for the development of asynchronous and production-ready services, offering automatic deployment for ML models.

Some remarkable characteristics:

  • Generic classes for API resources with the convenience of standard CRUD methods over SQLAlchemy tables.
  • A schema system (based on Marshmallow or Typesystem) which allows the declaration of inputs and outputs of endpoints very easily, with the convenience of reliable and automatic data-type validation.
  • Dependency injection to make ease the process of managing parameters needed in endpoints via the use of Components. Flama ASGI objects like Request, Response, Session and so on are defined as Components ready to be injected in your endpoints.
  • Components as the base of the plugin ecosystem, allowing you to create custom or use those already defined in your endpoints, injected as parameters.
  • Auto generated API schema using OpenAPI standard.
  • Auto generated docs, and provides a Swagger UI and ReDoc endpoints.
  • Automatic handling of pagination, with several methods at your disposal such as limit-offset and page numbering, to name a few.


Flama is fully compatible with all supported versions of Python. We recommend you to use the latest version available.

from flama import Flama

app = Flama(
    description="My first API",

def home():
        - Salute
        Returns a warming message
        This is a more detailed description of the method itself.
        Here we can give all the details required and they will appear
        automatically in the auto-generated docs.
            description: Warming hello message!
    return {"message": "Hello 🔥"}

This example will build and run a Hello 🔥 API. To run it:

flama run examples.hello_flama:app
