Everything is a

Dynos are the main Heroku products. Each dyno is a virtualized Linux container. That makes scaling easier since you can increase or decrease the number of used dynos, manage its size and type.

Is Heroku good for Jamstack?

Heroku is not made for static-first Jamstack projects. It doesn't have its own CDN. You can integrate it with 3rd-party networks like Amazon CloudFront, but that requires more steps and hassle. It's too complicated to host a static website, and there are many better and cheaper options.
