Cloudflare has rebuilt its Containers service to better support agent workloads. The new version allows for on-demand sandbox creation, faster startup times, and filesystem snapshots. This update is aimed at developers who need a full Linux workspace for their agents.
Key facts
| Fact | Detail | The source says |
|---|---|---|
| Startup Time Reduction | 6x faster | “Containers start 6x faster” |
| New Scheduling Policy | Moves control over each sandbox into application code | “A new scheduling policy moves control over each sandbox into application code” |
| Filesystem Snapshots | Available in public beta | “filesystem snapshots are available in public beta” |
What happened
Cloudflare has announced significant improvements to its Containers service, designed to enhance programmability and performance for agent workloads. The new architecture enables agents to create sandboxes on demand, choose the image and instance type at runtime, and achieve faster startup times. Containers now start 6x faster, as demonstrated in ComputeSDK's benchmark, reducing median startup time from over four seconds to 648 milliseconds. Additionally, filesystem snapshots are available in public beta. These changes build on Cloudflare's existing Durable Object technology, which provides a persistent controller for each container. The update also introduces new capabilities to the native ctx.container API, allowing Durable Objects to control Containers directly. This makes Containers a better fit for use with Workers, Dynamic Workers, and Durable Objects when agents require a full Linux workspace.
What to weigh
- Containers start 6x faster, as shown in ComputeSDK's benchmark.
- Filesystem snapshots are available in public beta.
