About Krova Cloud
Krova Cloud is a cloud computing platform that runs any application inside its own isolated microVM, called a Cube. Each Cube is built on Firecracker, the same isolation technology behind AWS Lambda and Fargate, giving you the security of a virtual machine with the speed of a container. Cubes boot in under a second, have their own kernel, no public IP by default, and full root SSH access.
What problem does it solve?
Traditional VPS providers and containers leave you with a dilemma: shared kernels from containers create security risks, while VPSs are slow to provision and come with complex networking setups. Krova Cloud eliminates this by offering a real virtual machine with its own kernel and per-cube jailer sandbox, booted in seconds. There are no VPCs, security groups, or IAM to configure — you create a Cube from the dashboard or terminal and SSH in immediately.
Who is it for?
Krova Cloud is ideal for developers running untrusted user code, AI agents needing disposable sandboxes, teams looking for ephemeral CI/CD environments, and anyone running Docker or container workloads in isolation. It's also a fit for side projects and APIs that need to scale down to zero. It is not for users who want a managed control panel — that's the upcoming Nest product, and traditional shared hosting users should wait for Nest to launch.
Real use cases
Give every end-user their own isolated Cube to run untrusted code safely. Let AI agents install packages and browse filesystems inside disposable full-root environments. Boot clean build or test environments for CI pipelines in seconds, then tear them down — every run starts from a pristine microVM.
Key features
- Firecracker microVM isolation — Each Cube has its own kernel and jailer sandbox, never a shared kernel, so one workload can't affect another.
- Boots in seconds — Create and SSH into a fresh server in under a second, perfect for ephemeral workloads.
- Private by default — No public IP assigned unless you open ports, and every open port can be IP-allowlisted.
- Per-minute billing — Only pay for compute while your Cube is running; power off and charges stop instantly.
- Full root SSH — Complete control over your own kernel, any size you want (vCPU, RAM, disk combinations are flexible).
- One-command provisioning — Create and manage Cubes from the dashboard or your terminal with the krova CLI.
- Flexible sizing — Any vCPU / RAM / disk combination, from 1 vCPU and 1 GB RAM upward.

What is a Cube in Krova Cloud?
A Cube is a lightweight microVM built on Firecracker. Each Cube boots its own kernel in complete isolation from others, giving you the security of a virtual machine with the speed of a container, plus full root SSH access.
Who is Krova Cloud best for?
Developers running untrusted user code, AI agents needing disposable sandboxes, teams needing ephemeral CI/CD environments, and anyone running Docker or container workloads that require strong isolation and per-minute billing.
What are the best Krova Cloud alternatives?
Krova Cloud is up to 69% less expensive than comparable VPS offerings from AWS Lightsail, DigitalOcean, Vultr, or Linode. It differs from those by giving you the isolation of a VM with container-like boot speed and per-minute billing.
What is the main limitation of Krova Cloud?
Nest, the managed hosting product with a control panel, is not yet available — plans are still being finalised. For now, Krova Cloud is a developer-focused platform requiring terminal/SSH familiarity; it has no managed web hosting option yet.
