I just stumbled across this site, and instantly thought of all the skinners who have to suffer through gimp's interface to get access to photoshop-like features.

It's basically a javascript version of photoshop. I'm sure it's not all there, but everything I could thihnk of was there, worked, and more importantly, worked identically to photoshop.

Yeah. Photopea is one of the better one's. I know the developer of photopea did an AMA on reddit the other day. Pretty interesting stuff.

Some context first. AMA (I Am A) is a subreddit where people can talk about their accomplishments, creations or things they have done. I'm sure you get the point.

Another great and useful editor (that i've used myself), also pretty close to being photoshop:

That's where I found it, but I suffer from a bit of input lag
