Why Wire Is Moving Off Cloudflare Durable Objects for Better AI Performance

Why we're moving off Cloudflare Durable Objects

We are rebuilding Wire's container runtime to solve four structural limits of Cloudflare Durable Objects, specifically around vector indexing, compute proximity, and self-hosting. By moving to our own infrastructure on Fly Machines with embedded SQLite, we achieve faster retrieval and true isolation. While we still rely on Cloudflare for our API and control plane, this shift allows us to offer dedicated capacity and better durability for regulated teams.

"Durable Objects hand you durability and single-writer consistency for free, and leaving means buying them back."
