- Wire, a context container service for AI agents, is moving off Cloudflare Durable Objects due to four structural limits.
- Limitations include the vector index being separate from the object, compute not being next to data, placement being static at creation, and inability to self-host.
- Wire built a new runtime using Bun on Fly Machines, with each container as an SQLite file embedding a vector index via sqlite-vec for in-process retrieval.
- The new system offers improved retrieval performance, placement flexibility, and better isolation for paid workspaces.
- Durability is ensured through continuous WAL shipping, and the transition maintains the same API and user interface.
