Is there a web version free or just Desktop with Web instructions?

✅ YES — there is a free Genymotion Desktop edition, but it is for PC and Mac, not a web version. The cloud/web options are separate products and are not free, though they may offer trials.

You can use the free desktop edition for personal use only, with limited features and no technical support. To get it, download from Genymotion Desktop download and follow the quick start guide.

The web-based options are Genymotion SaaS and Genymotion Device Image, and both are paid products with free trials available.

Are you looking for something to test apps locally or to run devices in a browser for a team?
