Summary

Celld is an open-source daemon that runs Cloudflare Workers and Durable Objects on self-hosted infrastructure, using S3-compatible object storage as the sole coordination mechanism without consensus protocols or control planes. Each object is backed by its own SQLite database, sharding by construction to eliminate single-database contention and blast-radius failures, with idle cells hibernating to near-zero resource usage. Nodes embed V8 to execute Wrangler bundles, use S3 compare-and-swap for lease ownership, and continuously replicate cell state to the bucket, making nodes fully replaceable.
