This repository contains an ASL Workflow Engine that provides a Local Step Function implementation exposing the AWS Step Function API and supporting AWS CLI and SDK calls.
In addition to the ASL Workflow Engine this repository provides a GUI for creating Step Functions in the form of a drawio Docker image bundled with the https://github.com/sakazuki/step-functions-draw.io Step Functions Plugin.
The repository also contains links to a range of useful resources about the Amazon States Language (ASL), including GUIs and possibilities for calling out to alternate serveless frameworks such as Fn or OpenFaaS or whatever.
