What's Good
Apache-2.0 (denoland/celld), release v0.6.2. Gives you the Durable Objects programming model without being tied to one edge platform, and spreads objects across a cluster of nodes. Useful for chat rooms, collaborative documents, rate limiters and other per-entity state. ★~5.4k.
The Catch
Pre-1.0, so expect API changes between releases. A write only counts as durable once it reaches S3-style object storage, so you need a bucket even for a small setup, and write latency depends on that store.
Verdict
Durable Objects you can self-host — promising, but pin versions and plan for an object-storage bucket from day one.
