Consider Kleki as a photoshop alternative

[Fish49]

Kleki is a well-made, stable, web-based alternative to photoshop. it is dense with features, open-source, and actively maintained by Bitbof. I use kleki for nearly every 2D art project I do unless i need animation or vector tools.
Here is its github link: https://github.com/bitbof/klecks
And you can access it on the web here: https://kleki.com/
I definitely recommend kleki, as it has never given me any trouble and its always getting improvements.
