Thanks for linking these other projects - I'm going to add a section in my README linking to other projects that people might find useful for their various use cases.

Go-task feels like a build tool and not really a general task runner.

Looks like Just brings a lot of similar features and I will definitely be looking into it deeper. However it still touts itself a build-tool at heart.

Run is NOT trying to be a build tool - It wants to be a script/wrapper manager and so the feature set is trying to optimize for that.

Thanks for the question - I hope that helps - Please let me know if you have any other questions or comments.

BTW: Can you link to your "own personal task runner" ? I'd love to see it and others might find it useful, too.
