Many other image-editor apps do now take Fireworks' same non-destructive hybrid editing approach... kind of. But they're always missing one thing or another. Either:

1. they aren't multiplatform (can't get "standard" adoption like Fireworks if you're macOS-only)

2. they don't go far enough with the vector editing capabilities (e.g. Fireworks allows you to apply arbitrary gradients/textures/other image assets as the stroke and fill of vector shapes)

3. they don't go far enough with the non-destructiveness (e.g. Fireworks applies filter-effects to both vector and raster layers, as non-destructive "filter layers" bound to a parent layer — effectively "functional lenses" for images; can edit the base layer "underneath" these transformation layers, and see the transformed output change as a result. Of course, you can always "flatten" the transformations into the layer, to then edit the post-transformed version of the layer. Though IMHO this could be taken even further, with "brush modifications" being just another kind of transformation layer!)

4. they use project file formats that consist of entire directory bundles, or file formats opaque to the OS preview mechanism. Fireworks just stored projects as an extension chunk of a PNG file; and every OS knows how to preview PNG files. (And, if you didn't care about the project, you could just treat the PNG file as a PNG file, putting it through ImageMagick or MSPaint or whatever, which would strip the optional chunks, thus "exporting" the project to PNG without needing the program that created it!)
