Dependent on use case. #adobeexpress is the next commercial and sadly bigtech solution for the typical canva use case. #unplugbigtech

If you want open source and self hosted https://aktivisda.earth/ could be an idea. But it is for activist movements. #akitvisda

@penpot can be used like this but isn't as easy as drag and drop like #canva is. Comparable to #figma. You can easily set it up locally with #docker.

#PolotnoStudio seems to be a self-hosted alternative as well. But I'm not sure how easy it is to set up and use. https://polotno.com/

For complete graphic design locally I would go for a mixture of @GIMP @Krita @inkscape. You can basically create the #content design for everything just with those three.
