Is it possible to run the playground as a website or is the electron app the only option?

yes, u can open it as a website u need to deploy ur app, start it and just open link

I want to deploy it to openshift as a website. I don't want to deploy an electron app anywhere

You don't need to deploy Electron. Every Prisma service exposes a HTML version of the Playground, if you HTTP GET the service endpoint (open the endpoint in your browser).

ok thanks. I'll give that a go
