Async API



This implementation is still in development. Contributions are welcome!

The Async API is an implementation of the Langflow API that uses Celery to run the tasks asynchronously, using a message broker to send and receive messages, a result backend to store the results and a cache to store the task states and session data.


The folder ./deploy in the Github repository contains a .env.example file that can be used to configure a Langflow deployment. The file contains the variables required to configure a Celery worker queue, Redis cache and result backend and a RabbitMQ message broker.

To set it up locally you can copy the file to .env and run the following command:

docker compose up -d

This will set up the following containers:

  • Langflow API
  • Celery worker
  • RabbitMQ message broker
  • Redis cache
  • PostgreSQL database
  • PGAdmin
  • Flower
  • Traefik
  • Grafana
  • Prometheus


To run the tests for the Async API, you can run the following command:

docker compose -f docker-compose.with_tests.yml up --exit-code-from tests tests result_backend broker celeryworker db --build

Hi, how can I help you?
