Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

You might not need a CRDT
This is an implementation problem with automerge. I wrote a blog post last year about CRDT performance. I re-ran the benchmarks a couple months ago. Automerge has improved a lot since then, but a simple benchmark test (automerge-perf[1]) still takes 200MB of RAM using automerge-rs. Yjs and Diamond types can run the same benchmark in 4mb / 2mb of ram respectively.
I've had a chat with some of the automerge people about it. They're working on it, and I've shared the techniques I'm using in diamond types (and all the code). Its just an implementation bottleneck.

CRDT-richtext: Rust implementation of Peritext and Fugue
Diamond types author here! Congratulations on getting your crdt working! It’s lovely to see a new generation of CRDTs which have decent performance.
And nice stuff implementing peritext! I’d love to do the same in diamond types at some point. You beat me to it!
Im building a little repository of real world collaborative editing traces to use when benchmarking, comparing and optimising text based CRDTs[1]. The automerge-perf editing trace isn’t enough on its own. And we’re increasingly converging on a format for multi user concurrent editing traces too[2]. It’d be great to add some rich text editing traces in the mix if you’re interested in recording something, so we can also compare how peritext performs in different systems.
Anyway, welcome to the community! Love to have more implementations around!
