Managed FOSS infrastructure for communities that care about how it's built

You're building something together — a cooperative, an open source project, a small team, a learning community. You need shared infrastructure that fits your values.

Not a VC-backed SaaS that will change the terms next year. Not a platform that shows ads to your members. Not a tool that holds your data hostage.

GROWbox runs on FOSS throughout. Your data stays in Markdown files. You can leave whenever you want and take everything with you.

What you get

Shared GROOV garden — a GRAV-based CMS without a database. Multiple contributors can edit the same instance. All content in plain Markdown files, versioned and exportable.

Your own domain and email — professional infrastructure that's yours, not a subdomain of someone else's platform.

ARM servers in Germany — Hetzner infrastructure, DSGVO-compliant, ~40% more energy-efficient than x86.

Fully portable — if you ever want to self-host, you take your Markdown files and run GRAV anywhere. No migration cost. No data loss. No lock-in.

How communities use GROWbox

Documentation gardens: Keep your project docs in a living, searchable knowledge base that any contributor can update.

Community knowledge hub: Curate resources, tutorials, and guides for your members. GROOV's flat-file structure makes it easy to contribute via text editors or the admin UI.

Cooperative transparency page: Publish meeting notes, decisions, financial summaries, and member governance documents in a way that's readable and maintainable.

Learning cohorts (Sprout+): The Sprout plan includes access to lernreise.tech — a guided learning platform for peer groups. Host a learning journey for your community.

The cooperative model

GROWbox itself is part of foss.systems — a cooperative infrastructure project. Your subscription contributes to shared infrastructure that benefits all gardens on the cluster.

This isn't rhetoric. It's architecture:

• One K3s cluster. Many gardens. Shared maintenance cost.
• Revenue is transparent. Nothing is extracted to investors.
• FOSS licensing throughout. The code we use is the code you can inspect.
