If you’re happy with the feature set of ~Photoshop CS2 you may want to check out Photopea [0]. It runs in your browser, has a similar UI to Photoshop and (for me) has all bells an whistles. It’s also open source [1].
Photopea is not open source, it says that in the description of the repo. They use GitHub for feature requests and bug reports.
Sorry, you’re totally right, I just quickly searched for “photopea source” and found the github page.
Photopea is not OSS, it is freeware Web App.
Ad supported. I think they got an ad free paid version. Been using it for years and I believe it covers over 90% of non professional photoshop use cases.
Photopea will probably never have 32-bit support because of browser limitations.
