 MetaBuilder is an ultra-generic, data-driven multi-tenant platform where **everything flows through the database**. No hardcoded routes, no component imports, no assumptions—the entire application structure lives in the database, rendered by a generic JSON-to-React engine.

+This vision evolved from our original Spark-based admin panel generator (see [Project History](#project-history)) into a more scalable, enterprise-ready platform with enhanced multi-tenancy, security, and flexibility.

+## Project History
+
+### Evolution from Spark-Based Version
+
+MetaBuilder began as a Django-style admin panel generator built on GitHub's Spark framework. The original version (preserved in `/old` directory) demonstrated the core concept of declarative, data-driven application building but was limited in scope and scalability.
+
+#### Original Version (Spark-Based) - Pre-2026
+
+**Architecture:**
+- **Framework:** GitHub Spark + Vite + React 19
+- **UI Library:** Radix UI components with Tailwind CSS
+- **Storage:** KV (Key-Value) storage via Spark
+- **Scripting:** Lua integration (Fengari) for custom logic
+- **Permission System:** 4 levels (Public, User, Admin, God)
+- **Scope:** Single-tenant admin panel generator
+
+**Key Features:**
+- Declarative schema definition via JSON
+- Auto-generated CRUD interfaces
+- Visual component hierarchy editor with drag-and-drop
+- Monaco code editor for Lua scripts
+- Page routing configuration
+- Database export/import
+
+**Limitations:**
+- No multi-tenancy support
+- Limited scalability (KV storage)
+- Single deployment architecture
+- No package system
+- No production-grade database support
+- Limited permission granularity
+
+#### Current Version (Next.js-Based) - 2026+
+
+**Architecture:**
+- **Framework:** Next.js 16 + React 19 + App Router
+- **UI Library:** Material-UI (MUI) with SCSS modules
+- **Database:** PostgreSQL (production) / SQLite (development) via Prisma ORM
+- **DBAL:** Dual implementation (TypeScript for dev, C++ daemon for production)
+- **Scripting:** JSON-based scripts with controlled execution
+- **Permission System:** 6 levels (Public → User → Moderator → Admin → God → Supergod)
+- **Scope:** Multi-tenant enterprise platform
+
+**Major Enhancements:**
+- ✨ **Multi-tenancy:** Complete tenant isolation with per-tenant data
+- ✨ **Package System:** 52 built-in packages with dynamic loading
+- ✨ **DBAL:** Language-agnostic database abstraction with credential isolation
+- ✨ **Production-Ready:** PostgreSQL, Redis caching, C++ services
+- ✨ **Enhanced Security:** 6-level permissions, row-level security, C++ credential isolation
+- ✨ **Scalability:** Docker deployment, Kubernetes support, multi-instance ready
+- ✨ **Testing:** Comprehensive test suite (464 tests, 100% pass rate)
+- ✨ **Type Safety:** Full TypeScript with Prisma ORM
+
+### Migration Path
+
+#### What Was Preserved
+- ✅ Core philosophy of data-driven architecture
+- ✅ Declarative component definitions (enhanced to JSON)
+- ✅ Generic rendering system (JSON-to-React)
+- ✅ Visual configuration capabilities
+- ✅ Schema-driven CRUD generation
+- ✅ Permission-based access control (expanded)
+
+#### What Was Reimplemented
+- 🔄 **Storage:** KV → PostgreSQL/SQLite with Prisma
+- 🔄 **UI Library:** Radix + Tailwind → Material-UI + SCSS
+- 🔄 **Scripting:** Lua → JSON-based scripts
+- 🔄 **Framework:** Vite/Spark → Next.js App Router
+- 🔄 **Architecture:** Single-tenant → Multi-tenant
+- 🔄 **Permissions:** 4 levels → 6 levels
+
+#### What Was Added
+- ➕ Multi-tenant support with complete isolation
+- ➕ Package system with 52 built-in packages
+- ➕ DBAL (TypeScript + C++ dual implementation)
+- ➕ Production deployment infrastructure (Docker, Nginx, Redis)
+- ➕ C++ media processing daemon
+- ➕ Comprehensive test suite (unit, integration, E2E)
+- ➕ Static site generation with ISR
+- ➕ Session management with expiry tracking
+- ➕ Remote package loading capability
+
+### Architecture Comparison
+
+| Aspect | Old (Spark) | New (Next.js) |
+|--------|-------------|---------------|
+| **Framework** | Vite + Spark | Next.js 16 App Router |
+| **UI Components** | Radix UI | Material-UI (MUI) |
+| **Styling** | Tailwind CSS | SCSS Modules + MUI sx prop |
+| **Database** | KV Storage | PostgreSQL/SQLite + Prisma |
+| **Scripting** | Lua (Fengari) | JSON Scripts |
+| **Permissions** | 4 levels | 6 levels |
+| **Tenancy** | Single | Multi-tenant |
+| **Package System** | None | 52 packages + dynamic loading |
+| **Deployment** | Single process | Docker + microservices |
+| **Testing** | Limited | 464 tests (100% pass) |
+| **Type Safety** | TypeScript | TypeScript + Prisma |
+| **Production Ready** | Dev only | Production + C++ services |
+
+### Why We Migrated
+
+#### Scalability Needs
+The KV storage approach limited our ability to:
+- Handle complex queries and relationships
+- Scale to thousands of users
+- Support multi-tenancy efficiently
+- Provide ACID guarantees
+
+#### Enterprise Requirements
+Production deployments required:
+- Robust database with transactions
+- Credential isolation (C++ DBAL)
+- Multi-tenant data isolation
+- Professional deployment options
+- Comprehensive testing
+
+#### Ecosystem Maturity
+- PostgreSQL provides battle-tested reliability
+- Prisma ORM offers excellent type safety
+- Next.js App Router enables optimal performance
+- Material-UI provides comprehensive component library
+
+### Legacy Code Location
+
+The original Spark-based version is preserved in `/old` directory for reference:
+- Documentation: `/old/*.md`
+- Source code: `/old/src/`
+- Configuration: `/old/package.json`, `/old/tsconfig.json`
+
+**Note:** The old version is maintained for historical reference only and is not actively developed.
