What engine does Sketchfab use to render the models?

A teacher of mine asked about this as I was showing them Sketchfab, and, well, I’m wondering myself.

Is it using an established engine or is Sketchfab using its own thing in the ‘player’?

Sorry if the question is completely malformed, but hopefully you know what I mean.

Hey @MarkA!

Our engine is built in-house. Parts of it are available as open source on (website removed - was expired)

Hope that helps!



Does the Engine are real- time render engine using server processor? or the software itself are able to render the model without any other support plugin

The engine is entirely real-time, and doesn’t require any plugin. It is using WebGL, which is standard technology built in all recent browsers.

Hello, I dont know if you’re aware of this already, but the site you linked to in your reply is a porn site.
Please fix this, I don’t want anyone else to have to bleach their eyeballs like I’ve had to


Wow, that domain must have expired. I’ll get rid of it right away, thanks for letting us know!
