Celld is an open-source daemon that enables self-hosting Cloudflare Workers and Durable Objects on private infrastructure. It addresses the limitations of shared databases by treating each object as an isolated SQLite database, with state replicated to an S3-compatible bucket for coordination. Nodes operate without a central control plane or consensus mechanism, relying instead on the object store for synchronization.
