Deno's Celld Runs Cloudflare Durable Objects on Your Own Machines

Celld executes Wrangler bundles on your own infrastructure, each Durable Object backed by its own SQLite database. The elegant part is what it omits: no control plane and no consensus protocol. Nodes embed V8 and coordinate purely through a shared S3-compatible bucket, using object-storage compare-and-swap to guarantee single ownership, with databases replicating continuously to the bucket as the durable source of truth. Idle cells hibernate to almost nothing. Apache 2.0, active development, compatibility surface still evolving. Landing the same day Cloudflare shipped an agent operating system built on that programming model, it neatly caps the lock-in question.
