Can someone explains what this site actually _does_?

  Think it runs a cloud hosted browser in your browser similar to browserling.com

Do these browsers have GPU? Is it built on the Chrome devtools protocol/puppeteer?

  No but I could add gpus to the machine. Good idea to try I guess. Yes it's built on top of chrome Dev tools.

    When I tried something similar I found that Googles profile-based compilation seemed to really affect performance of their builds, and with my own build I couldn't seem to match their performance, presumably because I didn't have as good a profile, but maybe because they had some spiffy compiler optimizations they were keeping close to their chest. Also, GPU is an economic requirement - it doesn't make a huge difference to user-percieved performance, but makes a big difference to CPU used, since all the render worker threads suddenly drop from 100% CPU to near zero... That lets you put more users on the same VM... There are some ideas I was experimenting with trying to do 'remote rendering' - ie rendering work is sent to a remote machine with a GPU. I got it working for basic image/text rendering, but not webgl/canvas/video encode/decode... In general, a single GPU can handle hundreds of browsing sessions, whereas a CPU can only handle tens of sessions, so costs can be cut quite a lot by decoupling them. That and one can get better bin-packing by decoupling...

      That's great advice about GPUs. Thanks! I am seeing some lower CPU usage on a new machine with 4 Nvidia T4 GPUS I just set up. https://gpus.cloudbrowser.xyz https://gpus.cloudbrowser.xyz

        Doesnt seem to work with webgl, I tried with some old project of mine: https://coinminingstats.com/globe https://coinminingstats.com/globe Its pretty responsive otherwise though, really cool

        Thanks. I'll look into this

        Seems this is an open issue: https://bugs.chromium.org/p/chromium/issues/detail?id=765284 https://bugs.chromium.org/p/chromium/issues/detail?id=765284

I'm doing a similar project, and have a few ideas that might interest you - can you get in touch (contact details in my profile)?
