What is MemberJunction?

MemberJunction is a metadata-driven application platform that turns your database into a fully functional application — complete with auto-generated APIs, forms, security, and deep AI integration. Define your schema, and MJ generates everything else: typed entity classes, GraphQL endpoints, Angular UI components, validation, and audit trails.

What makes it different: 175 modular TypeScript packages that work together or independently, 15+ AI providers behind a single abstraction layer, and an agent framework for building autonomous workflows — all driven by metadata, not boilerplate.

// Three lines to load, modify, and save any entity — fully typed, validated, and audited
const md = new Metadata();
const customer = await md.GetEntityObject<CustomerEntity>('Customers');
await customer.Load(customerId);
customer.Status = 'Active';
await customer.Save(); // Triggers validation, audit logging, and downstream actions automatically

// Swap AI providers with zero code changes
const ai = new AIEngine();
const result = await ai.ChatCompletion({
  model: 'gpt-4o',          // or 'claude-sonnet-4-5-20250929', 'gemini-pro', 'llama-3', ...
  messages: [{ role: 'user', content: 'Summarize this quarter\'s metrics' }],
  data: await rv.RunView({ EntityName: 'Quarterly Reports', ResultType: 'simple' })
});
