Does the Github Pages app support deploying a Next.js app from Github?

Or is it only jekyll?

If not, is there any way for me to do this without deploying a custom app in a docker container?

Yes, it's only jekyll. Not an expert on next.js but I think it also needs a backend right ? If so, you have to create a custom package - https://docs.cloudron.io/packaging/tutorial/
