I don't think Framer did as well as they were hoping.

The whole react component thing didn't turn out to be the killer feature collaboration was for figma. Framer has a lot of cool stuff, their plugin system is really powerful So you can have things like 3d elements which is super cool.

I am sure people use it, but it didn't grow in popularity like Figma did. I think with any kind of product, there's often a world of stuff happening under the surface that leads to success. I don't know why Framer hasn't been as successful. One guess would be that people just don't find writing react components and tying it to their design tool to be useful. Potentially too much friction, or that the people doing the designing don't often write react code. Or maybe they didn't market it well enough.

The question of components in design is really interesting but it's a whole other issue.

I do know that along with Adobe XD, Framer has had some issues with bugs. Figma, I would expect, is a lot more stable because they have their own custom renderer that's one canvas element whereas other tools use the DOM. It's one of the reasons why Figma is so feature-poor, they have implement a lot of behavior themselves.
