We are a group of performance-obsessed infrastructure architects. In an era dominated by virtualization, we chose to return to the physical layer — opening every real Apple Silicon bare-metal machine directly to serious developers worldwide.
For the past decade, the core logic of cloud services has been "sharing and virtualization." The hypervisor layer brought elasticity, but also introduced unavoidable overhead at the I/O level. For iOS compilation and local AI inference tasks that rely heavily on Metal, Secure Enclave, and native instruction sets, virtual machines are pure poison to efficiency.
CALMVPS was born from a refusal to compromise. We chose the harder path: deploying vast quantities of Apple Silicon bare-metal hardware in Tier-3 data centers worldwide, then delivering that clean computing power directly to you.
At CALMVPS, we do not believe in compromise.
No overselling, no sharing. Every core and every GB of memory you rent is dedicated physical hardware — delivering unwavering stability for Xcode 16 and local AI inference.
Hardware-level tenant isolation built on Apple native Secure Enclave and physical isolation architecture. Upon lease expiration, a DoD 5220.22-M standard physical overwrite is performed, ensuring your code assets are never exposed.
Say goodbye to complex traffic bills and hidden fees. Subscribe flexibly by day, week, or month — hardware and network bundled at a transparent price, compressing the cost of enterprise-grade computing to the absolute minimum.
From Silicon Valley to Tokyo, we partner deeply with the world's top Tier-3 data centers. Through a highly automated MDM orchestration layer, we can spin up a brand-new physical Mac node anywhere in the world within minutes.
From a garage idea to a globally distributed physical cloud infrastructure.
The founding team validated the first Apple Silicon bare-metal scheduling prototype engine in-lab, achieving a fully automated physical provisioning process within 120 seconds and proving the feasibility of large-scale virtualization-free deployment.
Infrastructure expanded to Asia-Pacific core hubs (Singapore, Tokyo, Hong Kong) and dual-line North America. Launched the industry-first Thunderbolt 5 physical parallel cluster service, officially released and opened to developers worldwide.
Full lineup upgraded to M4 and M4 Pro chips. Established a leading position in cloud-native iOS compilation and MLX model inference, serving 500+ engineering teams across 20+ countries and regions.
At CALMVPS, every operational task must be definable in code. We embrace engineering culture and automation — from data center power scheduling to BGP route announcements, all encapsulated as elegant APIs.
We do not list fictitious executives or profile photos on this page.
CALMVPS operates through coordinated functions including infrastructure orchestration, network & security, and customer support — with tickets, documentation, and API status as the external source of truth. The engineering culture emphasizesobservability, automation, and API-first, not personal narratives.
Provisioning, scaling, and lifecycle management are all triggered via pipelines and APIs, minimizing human intervention and wait times.
Tenant isolation, routing policies, and end-of-lease erasure procedures all follow documented runbooks, with full compliance audit traceability.
Technical issues are resolved through tickets and documentation; critical incidents are escalated per SLA, with infrastructure availability synced to the status page.
Stop letting slow virtual machines waste every minute of your team's time. Get started now — minute-level delivery, pure and uncompromising.
