founder of windmill.dev here, a fully open-source alternative to airplane.dev

Congrats on the launch.

I am not sure that is accurate. Both airplane and windmill supports defining your task as plain backend code and deploying them from CI/CD using our respective CLIs. The react part that we both support is if you want to build more advanced views that goes past the need of a single form. One difference between airplane and windmill is that airplane require a yaml configuration to define the inputs while windmill automatically infer them from the main function signature. What mechanism do you use yourself?
