We use Gitlab for CI/CD which looks on the surface very similar to Github actions.
We’ve hooked it up with the RhinoScriptCompiler ( RhinoScriptCompiler CI/CD Pipeline Issues - Rhino Developer - McNeel Forum) to do things like automatically create Rhino plugins from grasshopper scripts and deploy them to our modellers.
At the moment, we’re interested in doing a similar thing with Speckle - see my other post: Running Speckle on Rhino Compute - Help - Speckle Community
