From what I’ve gathered, both Next.js and Sapper.js are less ambitious than Meteor and Derby. They require to write your own data access code by hand, by making HTTP requests or importing whatever server-side JavaScript libraries you need, while Meteor and Derby tried to provide the same model API on the server and on the client. Maybe the model API (and the fact that you were almost forced into storing everything in MongoDB) was the greatest limitation.
