In the works

Let AI agents build and deploy your app on your Mac. Then move it to the cloud.

ownpaas is a macOS app that runs a cloud lab on your Mac, with virtual servers, networks, load balancers, volumes, DNS, S3 and k3s clusters. The lab answers the Hetzner Cloud API, so the hcloud CLI, Terraform and coding agents work against it unchanged. Each agent gets its own project, and reset, checkpoints and a kill switch let it make mistakes safely. Move to Cloud then shows the monthly cost and exports the setup for your own cloud account.

How it works

Four steps, from your Mac to the cloud

The lab runs on your Mac and keeps running when you close the window. The gateway and what you move run in your own cloud account.

  1. Step 1, on your Mac

    Install the app

    On first start it downloads a Debian 13 image (about 290 MB), starts its engine and creates your first project.

  2. Step 2, on your Mac

    Connect your agent

    One click adds the ownpaas MCP server to Claude Code, Cursor, Codex or Claude Desktop. Or you copy HCLOUD_ENDPOINT and HCLOUD_TOKEN.

  3. Step 3: Prepare, on your Mac

    The agent builds

    It builds in its project with hcloud, Terraform or kubectl, and resets to a checkpoint when a try goes wrong. You see each agent's activity in the app.

  4. Step 4: Pre-publish and Publish

    Testers, then the cloud

    The gateway publishes the app from your Mac for testers. Move to Cloud then shows the monthly price and exports a Terraform plan to review.

What you get

A lab on your Mac, and a control panel

Every part says how far it is. ownpaas is not released; In testing means built and being tested in the app.

A cloud labIn testing

It speaks the Hetzner Cloud API: servers with snapshots and backups, networks, volumes, load balancers, firewalls, IPs, DNS and S3.

A project per agentIn testing

Each with its own token, its activity log and a kill switch. Up to 20 checkpoints per project, and a reset to start over.

A gateway for testersIn testing

A small server in your cloud account with a public address and a tunnel to your Mac, so testers can open an app that runs on your Mac.

An MCP server for your agentIn testing

With 10 tools: projects, checkpoints, a cost estimate and the export. Other MCP clients get the entry to paste.

Kubernetes and an app catalogPreview

k3s clusters, and a catalog of 4 apps (Umami, Forgejo, Vaultwarden, Listmonk) with backup and restore.

A control panelIn testing

For the lab and for your real cloud projects, which stay read-only until you allow changes.

Limits and privacy

Its limits, and what stays on your Mac

Limits

  • Macs with Apple Silicon and macOS 15 or later only.
  • A lab, not a public cloud: one region, reachable from the internet only through the gateway.
  • Move to Cloud has one target today, and the export does not carry disk contents.

Privacy

  • Labs, projects and checkpoints stay on your Mac, and the tokens in its Keychain. No telemetry.
  • The licence check sends the key, the activation id and the Mac's name, weekly.
  • Agents never get your cloud provider's token.

Where this stands

What is built, and what is left

ownpaas is not released and not on sale yet.

BuiltIn testing

The lab engine and the app, agent projects, checkpoints, the MCP server, licensing, and Move to Cloud's cost preview and export.

Left before the launch

Signing and notarizing the app, its update key, the Paddle product and a test purchase, the licence service, the public download, a lawyer's review.

Planned Move to Cloud into PaaSbox Clusters: a k3s cluster on one server in your own Hetzner project, created and kept current by the PaaSbox portal, at a planned €29 per cluster per month, incl. VAT; not bookable yet.
