It does need node js but it is super fast .. almost as good as native vim plugins ( if not faster ) .. and no dependence on GUI ..
They have sample config in readme file .. works on both nvim and vim ..
Thanks for the ⚡ s ☺️

Yeh, not crazy about that dependency, but good to hear it's fast. I did poke around the install docs. I don't see a clean way to drop it into my lazyvim config, but I'll keep digging.
https://github.com/neoclide/coc.nvim this is the one you need to drop into config .. I use vim-plug so not sure about lazyvim config but should work out in similar way ...
The link you shared is the market place built on Coc .. It is a good idea but I have no use of it :-)
Once you have the plugin installed .. :PlugInstall in my case with vim-plug - then you can install other coc-extensions .. for example :cocInstall coc-ltex for language tools .. there are tons of them which you can see at the market place ..
