What is Orbita?

Orbita is an open-source, self-hosted Platform-as-a-Service (PaaS) written in Go. It turns a single VPS into a fully isolated hosting environment for many client organizations — each with their own dashboard, projects, environment variables, secrets, logs, domains, databases, and resource quotas. Clients never see each other; you, the super-admin, see everything.

It ships as a single ~30 MB binary with the React dashboard embedded, and idles under 50 MB of RAM — leaving nearly all of your server for the apps you actually run.

The one-liner

One VPS. Many clients. Full isolation. Secure a server and deploy a full Grit app in two commands.

Two things in one

1. A multi-tenant PaaS. Deploy from a Docker image or a Git repo, with managed databases, cron jobs, custom domains + automatic TLS, live logs, metrics, an in-browser terminal, and per-organization resource quotas — all from one dashboard or the API.

2. The control plane for Grit Cloud. Because a Grit app has a known shape (declared in grit.json), Orbita can build, route, migrate, and observe it with zero hand-configuration. The grit cloud / grit deploy CLI sits on top and drives it.

What makes it different

  • True multi-tenancy — isolated Docker networks, per-org encryption keys, cgroup v2 quotas, and 4-role RBAC. The thing Dokploy and Coolify don't have.
  • Grit-awareness — Orbita doesn't treat a Grit app as an opaque container. It reads the shape and wires the build, addons, domains, and migrations itself.
  • Tiny footprint — a single Go binary, not a PHP/Node control plane.

Who it's for

  • Freelancers & agencies running many client apps on one cheap box with true isolation.
  • Solo Grit developers who want the fastest path from git init to a live, migrated, observable app — self-hosted, so it's nearly free.
