Cloudflare's Durable Objects escape the walled garden, set up shop in your S3 bucket

celld is an open-source daemon from the Deno team that executes Cloudflare Workers and Durable Objects on your own infrastructure. Each Durable Object is backed by its own SQLite database, replicated to an S3-compatible bucket you own. Nodes coordinate solely through object storage using compare-and-swap operations—no control plane, consensus service, or membership protocol required. Idle cells hibernate to near-zero resource usage, and the bucket serves as the durable source of truth while nodes remain fully replaceable.
