I'd describe it as "NeoVim for people who don't want to spend time configuring it". It has syntax highlighting (for pretty much any language you can think of) and LSP support out of the box. And the config file is just a TOML file. Here's my current config for example:
theme = "monokai_pro_spectrum"
[editor]
line-number = "relative"
middle-click-paste = false
[editor.statusline]
mode.normal = "NORMAL"
mode.insert = "INSERT"
mode.select = "SELECT"
That's it. No need to deal with Lua or VimScript
Also using commands after typing the : is easier than in NeoVim since Helix will show you a list of available commands and a description of the closest match (or the one you choose from the list with the tab key). It looks like this:
I use Helix for quickly editing files and coding
NixOS. There are lots of great things about it (like atomic upgrades, easy rollbacks, no dependency hell, safely mixing stable and unstable packages, and more) but it's killer feature is that (almost) everything about the system is specified in a single config file
