• Cloudflare rebuilds Containers for on-demand agent sandboxes with snapshots and 6x faster starts

  Cloudflare shipped a public beta of a new durable_object scheduling policy for Containers, aimed at agent workspaces created on demand: code now picks each sandbox's image and compute size at start time, and filesystem snapshots via snapshotContainer() let sessions resume or fork from one checkpoint. ComputeSDK's independent benchmark put median time-to-interactive at 648ms, down from 4.049 seconds, and a burst test started 100,000 containers in about 5.4 seconds. A new cloudflare/debian-trixie image (Debian Trixie Slim plus Node.js 24 LTS) lets agents start without building their own. Cloudflare says rollouts are now just code, with canary, pin, migrate and rollback per sandbox. The legacy Container and Sandbox classes stay supported through December 31, 2026.
