Open-source alternative to Durable Objects is welcome

Really interesting to see these new compute paradigms. I haven't built anything on Durable Objects yet but I can see the appeal and I'd prefer an OSS option. SqliteDB per tenant…
siliconc0w on HNI love the idea of DOs and I'm happy to see an OSS implementation. Would it be interesting to write about comparisons against Cloudflare Durable Object to the project README?…

Cross-actor query engine

How preemptive scheduling and fairness work
From 1 comment
How do you intend to conquer the preemptive scheduler? System-wide fairness and preventing starvation are essencial steps for this to work well.
