Cloud
Master Cloud
Master Cloud is a full-stack backend integrated directly into the editor. No account required, no setup, no API keys.
What is Master Cloud
Managed backend platform built on top of PostgreSQL and Deno edge runtime. For every project, you automatically get:
- Postgres database with schema and row-level security
- Auth system with email, Google, and session management
- Object storage for files
- Edge functions for server-side logic
- Secure storage for secrets
- Real-time logs
- AI Gateway for Gemini and GPT-5 models
Cloud is automatically enabled for every new project.
Why use it
- Zero setup — no credentials, no YAML, no CLI.
- Consistent with frontend — same environment, same typing, same debug.
- Production-ready — HTTPS, scalable, EU-hosted.
- Predictable pricing — usage-based, free tier to start.
Activation and region
Cloud is activated automatically upon project creation. The default region is EU (Frankfurt) — data never leaves the EU.
Services in Cloud

Permissions and security
Cloud follows the principle of least privilege. The Anon key can only do what RLS policies allow. The service role key only lives on the server (edge functions).
Never store the service role key in frontend code.
