Thread:Extension talk:VisualEditor/Using VisualEditor on shared hosting/reply (3)

It's highly unlikely you'd be successful getting VisualEditor to work on shared hosting. The biggest reason isn't VE itself, but the parsoid service that's needed to parse the wikitext/HTML.

Parsoid requires that you have node.js running in the background at all times. Most shared-hosting companies (HostGator, Bluehost, Dreamhost, etc.) don't allow you to do that. You are better served, for performance and security reasons, to use a dedicated hosting solution such as a VPS.
