Cloudflare Containers: containers arrive on Workers in public beta

2025-06-24 · Publisher : Cloudflare · Domain : Cloud & DevOps

Cloudflare opens Containers in public beta, letting developers start containers on demand from Worker code, on its global network, billed every 10 milliseconds of active runtime.

### Background On 24 June 2025, **Cloudflare** opened **Cloudflare Containers** in public beta for all users on paid plans. The Workers platform, centred until then on functions running in isolates, can now run containerized applications. Worker code starts container instances on demand. ### Key facts - Architecture: routing between Workers and containers, integration with Durable Objects (state), Workflows, Queues, R2 and Agents; global deployment ("Region:Earth"). - Three instance types: dev (256 MiB, 1/16 vCPU), basic (1 GiB, 1/4 vCPU) and standard (4 GiB, 1/2 vCPU). - Billing per 10 ms slice of active runtime: memory $0.0000025 per GiB-second, CPU $0.000020 per vCPU-second, disk $0.00000007 per GB-second; network egress $0.025 to $0.050 per GB depending on the region. - Beta limits: 40 GiB of memory and 40 vCPU concurrently; Cloudflare announces higher limits, larger sizes and global autoscaling to come. ### Why it matters Edge serverless long excluded workloads that need a full environment (native libraries, binaries, AI tooling). Containers fills that gap on the Cloudflare platform and brings the offering closer to Cloud Run or Fargate, with activity-based billing. For a services firm, it is one more option for intermittent workloads, to be compared on beta limits and platform lock-in. ### Takeaway Cloudflare bridges the gap between serverless functions and containers on its own platform.
