I’m mainly interested in managing virtual devices in the cloud, can you explain how that works?

Genymotion SaaS lets you create on-demand cloud instances, start and stop them from the web dashboard, and manage them from Genymotion Desktop’s Cloud tab too. You can also automate cloud device control with gmsaas, ADB, and CI/CD tools like GitHub Actions, Jenkins, CircleCI, Bitrise, and Detox.
