Cloudflare Containers, rebuilt to scale agent sandboxes

Today, we’re making Cloudflare Containers more programmable and optimized for agent workloads.

Proof1 independent outlet

Key points

  • Agents don't deploy sandboxes ahead of time.
  • So we rearchitected Containers to meet these requirements: your code can now choose each sandbox's image and instance type at runtime, Containers start 6x faster, and filesystem snapshots are available in public beta.
  • All of this builds on what has always set Containers on Cloudflare apart: every Container gets its own Durable Object, a persistent, programmable controller running right next to it that manages its lifecycle, outbound traffic, and more.
  • We are bringing more capabilities directly to the native ctx.container API, so the Durable Object can control its Container without a wrapper class in between, and we’re carrying this model into Sandbox SDK 1.0.
