A reminder that photopea.com is a great photoshop alternative and it's web-based
Photopea is great, and you can do a lot,
but it is not near the functionality of Photoshop.
However, most people do not need most of that.
The alternatives are getting better, but it always seems like there is one action that would be trivial in photoshop that always end up being impossible in the competitors, and it ends up being exactly the thing you need for your project.
