Beta A cloud for small software

Your AI wrote the app. Nanocloud gives it a home.

Paste the code, or let your agent deploy it over MCP. It's live at a URL in about ten seconds, isolated in its own container, and shareable like a Google Doc.

// how it works

From "my AI built this" to a link your team can open.

Nanocloud is the last mile. No regions, no build config, no Dockerfile, and nothing to learn about ports.

Build

Ask your agent for the tool you need, or paste code you already have. A single Python file, a multi-file project, a tarball or a git URL all work.

Deploy

Nanocloud detects the stack (FastAPI or Flask), starts it in an isolated container, waits until it's healthy, and routes it to its own URL.

Share

Hand out a revocable link, cap how many times it can be opened, or open it to your org. Revoke it whenever you want.

// built for small software

Everything a five-person tool needs. Nothing it doesn't.

Ten-second deploys

Four ways in (file, project, tarball, git), one runtime. Redeploying the same code is a no-op; changed code updates in place at the same URL.

Isolated by default

Every app gets its own gVisor-sandboxed container, capped at 256 MB, half a CPU and 100 processes, on a network where apps can't talk to each other.

Share like a doc

Read or write links that expire, have view caps, and can be revoked instantly. Every link is visible in one place, so nothing leaks quietly.

Self-healing

If a container dies, whether from a crash, a reboot or a stray docker rm, Nanocloud notices and revives it from cached source within about 30 seconds.

Data that sticks

Turn on persistence and your app gets a durable /data volume. It survives redeploys, restarts, even deleting and re-creating the app.

Know what it costs

CPU and memory are sampled every 30 seconds per app, with logs and a cost estimate one click away. No surprise bills from a forgotten prototype.

// for agents

The agent that wrote it can ship it.

Nanocloud ships an MCP server, so deploying becomes part of the same conversation that wrote the code. Your agent deploys, probes the live URL, reads the logs when something breaks, fixes it, and redeploys, all without leaving the chat.

// security

Private until you say otherwise.

AI-written code deserves a careful host. Every app starts private, and every widening of access is a deliberate, per-app choice.

  • Fail-closed access. Unknown or revoked credentials get nothing, and cross-account lookups return 404 so they can't reveal what exists.
  • Your session never reaches tenant apps. The dashboard session cookie is host-only, so an app can't read it, even one you didn't write.
  • Apps can't see each other. Inter-container traffic is disabled and container ports bind only to localhost.
  • Sandboxed with gVisor. Hosted apps run under gVisor's user-space kernel with every Linux capability dropped and privilege escalation blocked. Egress limits are next.Egress soon

Questions, answered.

Why not just use Render, Railway or Fly?

They're excellent, and they're built for developers who know what a port, a build step and a region are. Nanocloud assumes you pasted code from an AI five minutes ago and want a URL and a share link, not a dashboard with 47 tabs. If your app outgrows us, it's standard Python, so take it with you.

Can't my AI just deploy it somewhere?

That's exactly what we're for. Nanocloud is the tool your AI calls. With the MCP server, "build me X and put it online" becomes one conversation, and the agent can verify the live app and fix it if it's broken.

Is it safe to run AI-written code?

Every app starts private and runs in its own resource-capped container on a network where apps can't reach each other. On the hosted cloud, each container runs under gVisor with all Linux capabilities dropped and privilege escalation blocked. Egress limits are next on the roadmap.

What can I deploy today?

Python web apps: FastAPI and Flask, detected automatically. A single file, a multi-file project, a tarball or a git repository all work. More runtimes are on the roadmap.

Can I self-host it?

Yes. The same control plane runs as a hosted multi-tenant cloud or as a single-node appliance on your own box, with no fork. Talk to us if that's what your team needs.

Ship the small thing.

Your agent just built a tool. Give it a URL, a sandbox and a share link in one step.

We'll email you when your spot opens up.
