A developer has created an open source alternative to KWGT called Sukko.
It is an open source Android app for creating widgets for home and lock screens.
Here’s the project website: https://sadellie.github.io/sukko/
His repo: https://github.com/sadellie/sukko
Its currently in experimental stage and will take a while until a full release.
Current stage
Experimental
- Accessibility features are not implemented
- Expect huge changes in functionality
- Clean installation recommended. Data migration is not guaranteed
- External code contributions are welcomed, but I recommend waiting for alpha stage. There are no contributing guidelines at the moment
- Bug reports and feature requests are discouraged. I know what ku*tom is
- Not for daily usage despite implemented features and overall stability
- Please avoid redistribution on “free and open source android app repositories” 🟢🟦
Development updates: https://t.me/sadellie_dev
Compatibility
- Android 12 / API 31 and higher
- vivo - no, lol
- Pixel and close to AOSP ROMs
- Anything else - visit https://dontkillmyapp.com/ and follow instructions. If that didn’t help - open an issue or buy Pixel


I get that vivo phones aren’t supported, but the energy and messaging is very off here. “Vivo - no, lol” “open an issue or buy pixel”.
There’s no need to be a condescending dick to your users, you can just write “phones with aggressive task managers might kill the app and break updates”.
Plus I don’t think anybody sane is “buying pixel” just to access a widget app. 🙄
