Hello everyone,
NextGraph is a new platform that has just been released in alpha version, 2 months ago.
Apart form being local-first (CRDT based) and E2EE, NextGraph brings the Semantic Web into the picture so users and devs alike can directly interlink data, across documents, replicas, teams, and databases boundaries.
NextGraph is the only local-first Graph database out there, with E2EE, and with a powerful query language (SPARQL).
Each Document in NextGraph can be based on several available CRDTs. Yjs is one of them!
Try it out now: the app is release (webapp, linux, android, macos and windows)
The framework for programmers (JS, TS, Rust, Svelte, React) is almost ready and will be available within 2 months (end of 2024)
And on our website you can get more generic introduction
Let us know of your feedback and question, here or in our forum 
Looking forward hearing from you all soon.
Cheers
Niko, author of NextGraph
