Observable's biggest strength is its ability to provide an incredibly rich interactive experience for Data Viz. A lot of Data Viz applications are have too little control over the final product or are walled gardens which cannot be used anywhere else. The focus on code first Data Visualization tooling prvides a really usable experience
I would remiss if I didn't mention the excellent Observable plot, low code data viz library available in the notebooks. That makes it very easy to just drag and drop visualizations Review collected by and hosted on G2.com.
Offline support is a major blocker for our organization. Without offline support, I am unable to use observable for anything more than personal projects
A lack of data processing tooling is an issue as well. Admittedly this is a JS problem and Observable is indeed trying to solve it as well, its still a nagging issue.
Lack of dark mode support is also a bit of a bummer as it becomes difficult to stare at a sharp white surface for long Review collected by and hosted on G2.com.
