The canonical answer to this request is as follows: if you need multi-cursor (or, worse, multi-cursor with mouse support) then you are doing something non-Vim way (aka: wrong way) and there is a better way to do it.

If you need multi-cursor to do manual search and replace in text, then don't, just do automatic search and replace, maybe scoped to a block. If you need multi-cursor for refactoring or renaming a variable across entire source file, then don't, use LSP plugin (or switch to Neovim) and do the proper refactoring action.

Sure, there are legit cases of using multi-cursor in Vim, but they are rare. So it's not worth to put it into Vim itself.

Vim (kind of) has it though it doesn’t render the cursors:

Ctrl-V, then move down the lines you want to edit, Shift-I to insert text on multiple lines at once.

Multi cursor is on the neovim roadmap https://neovim.io/roadmap/

Funny, I used multiple cursor a lot back when I used Sublime Text, but stopped needing them when I switched to Vim.

There are plenty of ways to achieve workflows that can be done witg multiple cursors even in plain Vim: macros, :norm, visual blocks, :s, etc.

I'm curious to know what kind of editing you do that you need this so much?

How does it work?

I don't use it this way yet, but aider has a watch mode that would be fun with vim:

https://aider.chat/docs/usage/watch.html

I imagine with vim, from the document you're editing, you'd go:

:ter

to get a terminal. Fire up aider with --watch-files in the terminal. Hop back up to the file and start telling it what to do. Hit L when it's done to see the changes.

That's just a guess but after writing it out I kinda want to try it.

When I use aider it's via its chat interface and then I load the file with vim in another terminal tab to follow along but I think --watch-files with vim would be fun.

At least for Neovim, there are many official or community-made AI autocomplete plugins, and a bunch of chat interfaces as well

tmux + vim + Claude Code

The copilot plugin works well

AI makes advanced IDE features less relevant (or, more precisely, much easier to ignore or work without.)

I still have PyCharm, especially for working with data which I do a lot it helps quite a bit, but by default I'm back to a very vanilla Vim setup. Others have mentioned tmux which is great and I'd use anyway especially over ssh, but even just terminal tabs for instances of agents are fine frankly.

Avante.nvim is quite active

Wait a couple of more months, and no-none will know to write any other way.

That's pretty nifty. Link please
