Helix was inspired by neovim. Though mostly the inbuilt LSP/tree sitter support. Its keybindings are a mix between what neovim has and kakoune, though closer to kakoune I think. The major advantage IMO that helix has over neovim is built in support for most things you need plugins for in neovim as well as sane defaults out the box. You don't need 10s of plugins and 100s of lines of config to get helix to work like a modern editor - it just does out the box. All you need to do is install the LSP server for the languages you are interested in and launch helix.

The major downside ATM is it has no plugin support at all. Which is not as bad as it sounds as it includes so much out the box that you would typically require plugins for in neovim. They are working on plugin support though so it is only a matter of time for this to be fixed. Currently I don't feel the need for any plugins when using it so IMO it is not a deal breaker for me or my workflow. But the need to manage large configs and sets of plugins had already become too cumbersome in neovim for my liking.
