durable-objects

camelAI rewrote their coding agent to run entirely in a Cloudflare Durable Object, using SQLite and R2 for filesystem and replacing bash with JavaScript. The migration from VMs reduced costs and latency, and the codebase is now open source.

Wire, a platform for AI agent context containers, is migrating from Cloudflare Durable Objects to a custom runtime on Fly Machines due to structural limits: vector index separation, compute-data colocation, placement flexibility, and lack of self-hosting. The new architecture improves latency and enables dedicated capacity.
