Why we're moving Wire off Cloudflare Durable Objects
Summary
Wire explains why it is moving away from Cloudflare Durable Objects to a self-built container runtime. The team cites four structural limits—external vector indices, data locality for compute, fixed placement, and the inability to self-host—as drivers for the rewrite. The new architecture uses per-region hosting, in-process retrieval with embedded vector indexes, and a data plane designed for better performance and controllable durability.
