What you can build on a Cube

A Cube is a Firecracker microVM with its own kernel — so it's at home running untrusted code and AI agents, and it's just as happy hosting your site, database, or game server. Whatever you build, it's isolated by design, with no public IP and automatic HTTPS.

Built for the Cube

Workloads the isolation model was made for

When code you don't fully trust needs a real, sealed computer, the Cube's own-kernel isolation is the whole point.

Multi-tenant platforms

Run user & untrusted code

Give every end-user their own isolated Cube. Each one is a Firecracker microVM with its own kernel, so one tenant's code can never see or reach another's.

Agents & code interpreters

Sandboxes for AI agents

Give every AI agent its own disposable computer with full root. Let it install packages, run shell commands, and browse a filesystem — all sealed inside an isolated Cube.

Build, test & preview

Ephemeral CI & dev environments

Boot a clean, isolated build or test environment in seconds, run the job, and tear it down. Every pipeline starts from a pristine microVM with nothing left over from the last run.

Containers, done safely

Docker & container workloads

Run Docker and Compose inside a Cube that has its own kernel. Your containers get a full, isolated microVM to live in — not a slice of someone else's host.

Everything a VPS does

The classic workloads, only better isolated

Everything you'd run on a VPS — with its own kernel, reserved resources, and nothing exposed to the internet.

Sites & applications

Web & app hosting

Host websites and applications on a Cube with custom domains and automatic HTTPS. Full root, its own kernel, and no certificates to manage.

CMS & publishing

WordPress hosting

Run a fast, isolated WordPress site on a Cube with full root. Its own kernel, reserved resources, custom domains, and automatic HTTPS.

JavaScript & TypeScript apps

Node.js & Next.js hosting

Deploy Node.js, Next.js, and other JS/TS apps on a Cube with full control. Any Node version, any process manager, your own domain with automatic HTTPS.

Low-latency multiplayer

Game servers

Run low-latency game servers on a Cube you fully control. Reserved resources, full root, and TCP/UDP ports you open exactly where you want them.

Postgres, MySQL & Redis

Databases

Run Postgres, MySQL, or Redis on an isolated Cube with reserved RAM and disk. Full root, its own kernel, and resources that are never oversold.

Pick a workload and launch a Cube

Whatever you're building, it starts the same way — create a Cube, SSH in, and go. The whole thing takes under a minute.
