What kind of alternative is this? How does it work? Does it have users?

What kind of alternative is this

• lightweight, focusing only on auto activation.
• implemented purely in fish
• uses inbuilt activate.fish, unlike virtualfish

how does it work

• I use a function marked --on-variable PWD to run on every directory change.
• If the there is a new virtual environment in that directory, we source the associated activate.fish script
• if we are instead leaving a virtual environment, we call the deactivate function

does it have users

I have three stars so probably a tiny number, but I do think it's useful and sufficiently different from the existing plugins. Also, the source gist is the top result for "fish shell automatically activate virtual environment".

It's certainly nice to have an alternative, but could you work a bit more on those docs? Add some descriptions, examples, and compare it to virtualfish. If you can add the shine, I'll do my part here. 💯
