I'd like to set up my own Scratch server. Initially this would be for testing but eventually for people to access.
I want to implement an extension that uses some 3rd party tools that require credentials, so I am unable to put the credentials into a github repository and share the extension that way.
Are there any documents for how to host a Scratch server?
thanks.

I found the answer, I believe.
One can run a server by following instructions here:
https://github.com/LLK/scratch-gui/wiki/Getting-Started

Now I'm wondering how to spin up a scratchX server….

ScratchR, the software that powered the Scratch 1.4 website, was open source, but it was complicated to set up, and now it's very, very out of date.

ScratchR2, the software that powers the old style pages with a smaller, darker blue navigation bar, is not open source at all.

scratch-www, the new web client that powers the new style pages with a larger, lighter navigation bar, is open source, but the API backend that's necessary to run an independent Scratch server is not.

So the short answer is you don't set up your own Scratch server.

ScratchX, on the other hand, is just a simple static website with no community features. You could serve the files contained the GitHub repository from your own web server, but you might have to modify the ScratchX editor source code to remove the github.io check and compile Scratch.swf yourself.

Thanks for the reply djdolphin.
Kind of a shame MIT folks put out something that's not open source. I wonder why?

They actually haven't put out the backend at all.
