Cloudflare Containers add runtime configuration and filesystem snapshots
Cloudflare says the new scheduling path starts sandboxes faster. Filesystem snapshots are in public beta and let agents save and restore their workspace.
TLDR
Cloudflare announced runtime image and instance selection for Containers, alongside filesystem snapshots in public beta. Its blog reports median startup falling from 4.049 seconds to 648 milliseconds in a ComputeSDK benchmark launching 100 sandboxes concurrently. The new features use the native ctx.container API within a Durable Object. Snapshots preserve files for later sessions; they are immutable and reusable.
