Ryan Dahl Launches celld: Self-Hosted Distributed Durable Objects Using SQLite
steren · x · 2026-08-09
Ryan Dahl (creator of Node.js and Deno) recently launched celld, an open-source implementation for self-hosted, distributed Durable Objects.
Core Architecture & Features:
- Self-Hosted: Run Cloudflare Workers and Durable Objects-like applications on your own VMs using the same JavaScript APIs and the familiar wrangler.jsonc.
- SQLite-backed: Every Durable Object gets its own individual SQLite database.
- S3 Coordination: Databases are replicated to an S3-compatible bucket controlled by the developer, which also coordinates the nodes.
- Minimal Ops: Eliminates the need for separate database clusters, placement services, membership systems, or consensus services.
Released on August 5, 2026, version 0.1.0 is an alpha available under the Apache 2.0 license. The author praises its architecture as highly inspiring for experimenting with stateful server coordination, though it is not yet recommended for critical production systems.
