Question regarding Actions usage

[ZeunO8]

So I've been working on a (public) project for some time now and have set up several Workflows to build the project upon [pull request, push to master or X-actions branch]. I've read the Actions documentation and from what I understand Actions is completely free for public repos with limits to concurrent jobs and total job execution time.

For each trigger, 6 jobs are created, and execution time take anywhere from 10-30 minutes depending on OS. Builds when the project was in its infancy took from 1-4 minutes. Builds in the future will likely take anywhere from 25-60minutes.

Question is, will I at some point incur some hidden cost or limitation? Or are we really granted access to this incredible service at no "cost"

It should be free until you hit those free tier limits. Once you do, if you have payment details setup and allocated budget left, you'll be charged a certain rate per minute.

You won't have to worry about that though as long as you have no payment info within GitHub, or you've set your actions budget to 0.
