The name is OpenLara (https://github.com/XProger/OpenLara ) and you can try out the WebGL build directly on your web browser on: http://xproger.info/projects/OpenLara/ . The web version works amazingly well on my Pixel 7a with touch controls (you have to click on the “go fullscreen” button) using Firefox as a browser.
Tell that to Google with Google Docs, Microsoft with Office365, etc. The web applications are starting to become a thing in a big way.
When exactly has “large companies do that” become a good reason instead of a warning?
