I've been using act[1] as a tool to develop/test actions locally, which has helped a lot for creating new actions and debugging existing ones without incurring additional build costs.
There does appear to be some solutions on the marketplace that will allow you to ssh into a runner, but I haven't had a need for them as of yet.
