You Built It With AI. Deploy It Without DevOps.
You made something with Claude, Cursor, Bolt, or Lovable. Now give it a real backend — databases, file storage, user accounts — without touching a terminal.
Everything You Need to Know
What is a "backend"?
The part of your app that users never see but makes everything work — like databases, file storage, user accounts, and search. Without it your app only runs on one device.
What does OSC do?
OSC gives your app everything it needs to work for real users — database, storage, authentication — all running on open source software you can take with you. No vendor lock-in.
How does it work with Claude?
Claude can talk directly to OSC and set up what your app needs. You describe what you want, Claude handles the rest. No YAML, no dashboards, no DevOps knowledge needed.

File Sharing Service
Storage + web hosting
Paste this into Claude
“I need a file sharing service”
Claude sets up MinIO object storage and a hosted web interface so users can upload and share files.

Blog With Search
Database + search + hosting
Paste this into Claude
“Create a blog with search”
Claude sets up PostgreSQL for posts, Meilisearch for fast full-text search, and a web runner to host the app.
Estimated monthly cost: ~15 EUR/month

Common Questions
Do I need to know how to code to use OSC?
No. If you can describe what your app needs in plain language, Claude can set it up for you. OSC handles all the technical parts.
What is a "backend" and why does my app need one?
The backend is the part of your app that runs on a server — things like saving user data, storing files, managing accounts, and searching. Without it, your app only works on one device and cannot serve real users.
How much does it cost?
OSC has a free tier so you can get started at no cost. Paid plans start at 15 EUR/month when you need more capacity or services. Each starter project costs roughly 5–30 EUR/month depending on usage.
Will I be locked in? What if I want to switch later?
Never. OSC only uses open source software. You can export everything and run it yourself on any cloud provider at any time. There is no proprietary format or lock-in.
Does this work with Cursor, Bolt, or Lovable too?
Yes. OSC uses an open standard that works with Claude Desktop, Claude Code, Cursor, and any other AI tool that supports MCP. You are not limited to one AI.
