Cloudflare rearchitected Cloudflare Containers around agent workloads: application code can now pick each sandbox's image and instance type at runtime rather than at deploy time, startup is claimed 6x faster, and filesystem snapshots entered public beta. In ComputeSDK's independent benchmark, median container startup dropped from just over four seconds to 648 milliseconds; Cloudflare's own preliminary burst test created hundreds of thousands of containers in seconds. Every container still gets its own Durable Object, the ctx.container API now controls a container without a wrapper class, and the model carries into Sandbox SDK 1.0.

Why: If you run agent sandboxes — self-hosted or on a competitor — the 4s-to-648ms median startup number is the one to test against your own cold-start budget, because per-task image selection means you no longer pre-bake one image for a whole deployment. Filesystem snapshots in public beta are the piece that makes pause-and-resume viable, but it's beta, so treat it as a design option rather than a guarantee. The post names no pricing, region, or Malaysia-specific detail, so anyone building here still has to verify cost and latency from where their users are.
