use nodebb-plugin-write-api and you can create how many post you like using ajax instead socket.io

I want to install both Ghost cms and Nodebb on one VPS RAM512, is it okay?
Thanks for responding to me.
I doubt you would be able to run both. It depends greatly on how many users you have, but 512 MB would barely be enough for NodeBB. Why not use DigitalOcean? Their 1 GB plan is probably enough for both, but you'd be better off with 2 GB. If you use my referral link it will get you $20 worth of credit: https://m.do.co/c/3a45a3f20cb5
but Discourse and Nodebb are better source code so you?
Maybe you mean a comparison. I can give my personal view:
At the end of the day, both applications are really good and innovative, probably the best options for communities today.
