One of the most interesting things to me about CRDTs, and something that a skim of the article (with its focus on low-level CRDTs) might give the wrong impression on... is that things like https://automerge.org/ are not just "libraries" that "throw together" low-level CRDTs. They are themselves full CRDTs, with strong proofs about their characteristics under stress.

Per the Automerge website:

> We are driven to build high performance, reliable software you can bet your project on. We develop rigorous academic proofs of our designs using theorem proving tools like Isabelle, and implement them using cutting edge performance techniques adopted from the database world. Our standard is to be both fast and correct.

While the time and storage-space performance of these new-generation CRDTs may not be ideal for all projects, their convergence characteristics are formalized, proven, and predictable.

If you're building a SaaS that benefits from team members editing structured and unstructured data, and seeing each others' changes in real time (as one would expect of Notion or Figma), you can reach for CRDTs that give you actionable "collaborative deep data structures" today, without understanding the entire history of the space that the article walks through. All you need for the backend is key-value storage with range/prefix queries; all you need for the frontend is a library and a dream.

Automerge is an excellent library, with a great API, not just in Rust, but also Javascript and C.

This is true, I was able to quickly put together a Redis automerge library that supports the full API, including pub/sub of changes to subscribers for a full persistent sync server [0]. I was surprised how quickly it came together. Using some LLM assistance (I'm not a frontend specialist) I was able to quickly put together a usable web demo of synchronized documents across multiple browsers using the Webdis [1] websocket support over pub/sub channels.

Automerge is a great project, but it feels still way to academic in it's setup. If you need a superior DX and CRDT-based full-stack database, I'd recommend you to look at Triplit.dev and their docs. (while development has decreased somewhat, the product is in a fully-featured phase and should work well for anything from small to medium, probably also very large projects depending on your configuration). Give it a try, you will like it.
