I was expecting to see some verbose LLM output, but actually the code has a distinctly hand-crafted feel. Nice to see! I'm not sure if "production ready" is a safe claim 7 commits in to a project ;)
DAG Workflow Engine
A production-ready DAG (Directed Acyclic Graph) workflow engine driven by a YAML DSL. Validates, executes, and visualizes workflows with support for parallel execution, retries, conditional branching, batch iteration, and pluggable actions.
Type-safe code. Workflows are not configuration! If I wanted YAML hell I could stick to Github Actions.
But that's only the start. There are a lot of other things I would expect of a new workflow orchestrator in 2026 so if you are not comparing yourself to the competition you probably don't know what you're getting yourself into.
Yeah, that makes sense. I looked at a few workflow orchestrators and I'm building something that I will release soon, but my thinking is that the "workflow engine" should be an abstraction that takes the input and executes the steps. "What" you use to define that workflow is probably the SDK layer though, but I can certainly see the value in using type safe code to define as opposed to a YAML file.
I'm mainly focusing on the portability aspect of it (e.g. use TS/Python/etc. to define the workflow/steps or just simple a simple YAML file).
how it compares to airflow?

What makes it production ready? What's the code coverage on your tests? There are only seven commits in this repo as of this comment.

I don't see any references to existing orchestrators, which are way more complete, so I presume you did this as an exercise?
Just seeing YAML used for workflows in this age makes me automatically nope out.
Curious, what format would you prefer to use to represent a workflow instead of YAML?
