Problem
Traditional cloud compute platforms suffer from slow cold-start times, often taking seconds to minutes to spin up new instances, which severely limits the responsiveness of sandboxes, AI agents, and other latency-sensitive workloads. Additionally, low instance density per server drives up infrastructure costs and reduces the economic viability of running large-scale, short-lived compute tasks.
Solution
Unikraft Cloud delivers a specialized compute layer that cold-starts any workload in under 10 milliseconds, enabling near-instantaneous provisioning of sandboxes, AI agents, and other dynamic applications. The platform achieves up to 100,000+ VM instances per server through lightweight unikernel technology, providing VM-grade isolation without the overhead of traditional virtualization. Its advanced snapshotting technology allows users to fork a live virtual computer—including databases, sub-agents, and parallel headless browsers—in milliseconds, dramatically accelerating parallel workflows. The platform offers flexible deployment options including on-premises, bring-your-own-cloud (BYOC), and dedicated hosts, giving teams full control over their infrastructure stack while reducing compute costs by 10-100×.
Target Audience
Primary customers are engineering teams building sandbox environments, AI agents, and latency-sensitive applications that require rapid scaling, as well as platform teams seeking high-density, cost-efficient compute infrastructure for parallel workloads.
