celld is an open source, self-hosted implementation of Cloudflare Workers and Durable Objects that uses S3-compatible storage, SQLite, and Rust's Tokio runtime. The project aims to provide the same stateful serverless model without vendor lock-in and potentially at substantially lower cost, though Cloudflare disputes the reported savings.
