⚡ Key Features

✅ Cloud or Self-Hosted — Your Backend, Your Rules

Use the managed Supabase Cloud for simplicity or deploy your own Supabase stack for full control, privacy, and long-term scalability.

✅ Instant Login Systems – Plug & Play UI

Includes customizable Blueprint-based login widgets (email/password, OAuth) for drop-in authentication and session management.

✅ Persistent Actor System

Easily persist actor states across game sessions. Mark any actor as persistent, and Supabase handles storage, session sync, and live updates.

✅ Persistent Map Support

Save entire maps (or parts of them) as structured JSON and reload them dynamically from Supabase — ideal for sandbox games, user-generated content, or custom world building.

✅ Real-Time Gameplay Sync

React instantly to backend data changes — leaderboards, game state triggers, player status, and more — using Supabase's built-in real-time Postgres sync.

✅ Built for Blueprints & C++

Full Blueprint node library with async support, plus an extensible C++ API (SupabaseClient, SupabaseConnection, and more) for advanced developers.

✅ Secure & Scalable Architecture

Leverage Supabase's built-in security features like row-level security (RLS), role-based access control (RBAC), and authenticated queries — all from Unreal.

✅ Session & Token Persistence

Automatic session management via local save and token refresh — players stay logged in and authenticated across sessions.

✅ Mobile Support (Android/iOS)

Deploy your games across all platforms with consistent backend functionality.
