Millisecond Mirror (1ms.run) is a China-focused Docker image acceleration platform operated by Hefei Muleiwu Information Technology Co., Ltd. It helps developers and teams pull container images more quickly and reliably, reducing delays caused by slow or timed-out downloads. The service accelerates access to major image sources, including Docker Hub, GCR, GHCR, and Quay, and provides image search, setup instructions, and a one-step configuration option. It supports Linux, macOS, and Windows, making it useful for containerized development and CI/CD workflows.

The platform advertises download speeds up to ten times faster and reports 99.9% service availability. Its basic service is free, with additional traffic available for purchase on a pay-as-you-use basis; interrupted pulls are charged only for data already downloaded. Registered users can access a VIP download channel, while teams can share resources and manage them centrally. Millisecond Mirror also offers dedicated domains, documentation, pricing information, and user support, including a QQ group for technical assistance. Users are asked to clearly credit the service when referencing its mirror address.
