>I’m a “true believer” in CRDTs, which I have some experience in.

What is the largest-scale or highest-profile real-world usage of CRDT today?

(I glanced at this CRDT vs OT topic before but I'm not up-to-date on where things stand in the real-world performance: https://news.ycombinator.com/item?id=23988999)



Grandparent wrote a good article on CRDT performance https://josephg.com/blog/crdts-go-brrr/


It's not really high scale / high performance, but Apple's notes.app uses state based CRDTs internally for conflict resolution. It is perhaps high profile, since a lot of people are using it.


I'm not sure about the largest-scale single usage but the Phoenix Framework uses CRDTs for handing user presence.

It isn't enabled by default but it is very easy to use and the CRDT backend is basically hidden away.

TomTom uses CRDTs for their SatNav software.
