The cloud built around the Cube
Krova Cloud exists to make one thing effortless: running an isolated microVM with its own kernel. Every Cube is a Firecracker microVM — real isolation, no shared kernel — provisioned in seconds, billed by the minute, and reachable from a single API call. We handle the hypervisor, the networking, and the HTTPS so you can just ship.
What we believe
A short list of principles we don't bend on — they shape every part of the product.
Isolation by default
Every Cube boots its own kernel inside a per-cube sandbox — never the shared kernel a container hands every tenant on the box. Strong isolation isn't an upgrade you buy; it's the baseline for everything we run.
No surprises
Transparent per-minute billing, RAM and disk reserved 1:1 with the host, and pricing you can read in full before you sign up. Pause a Cube and compute billing stops instantly. No hidden egress traps, no fine print.
Developer-first
A typed TypeScript SDK, a CLI, an MCP server for Claude and Cursor, webhook verification, and a public REST API — all open-source. If you can script it, you can run a whole fleet of Cubes from it.
Honest simplicity
Simple but not simplistic. We describe the product in plain, truthful terms, keep the dashboard uncluttered, and default to sensible choices — so the easy path is also the right one.
What we're building
Firecracker gives you the isolation of a virtual machine with the speed of a container — but on its own it's just a hypervisor. Krova Cloud is the platform on top: provisioning in one click or one API call, per-minute billing, custom domains with automatic HTTPS, snapshots, and team access — VM-grade isolation without running the hypervisor yourself.
We're building the whole experience around the Cube — the dashboard, the SDK and CLI, the docs, and the billing — so that spinning up an isolated environment feels as light as starting a container, but gives you a real machine with its own kernel underneath. That's the product, and it's the only thing we're focused on.
