Is there an option to run emulators 24x7?

✅ YES — on Genymotion SaaS, instances can be started with a maximum run duration, so they can stay running until that limit is reached. The gmsaas instances start command supports --max-run-duration in minutes, and instances stop automatically when that limit is met: gmsaas Commands

For Genymotion Desktop, the emulator runs locally and the docs do not describe any built-in 24x7 hosting option. For always-on use, the cloud-based SaaS is the relevant product.

What are you trying to keep running continuously: an app test, a demo, or a monitoring job?
