What is MemberJunction?

MemberJunction

The open-source, AI-native data platform.

Unify your data. Add intelligence. Build AI-native apps on top of it.

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: 290+ 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.

It’s two things in one. A data platform for unifying and reasoning over your data — and a full-stack framework for building AI-native applications on top of it, where agents, prompts, and RAG operate directly on your entities. And because the whole stack is TypeScript with one object model that runs identically on the server, in the browser, in the CLI, and inside agents, you write your data and business logic once and run it on every tier.

Already getting your data into MJ and wondering what else you can build? MJ is a first-class platform for building AI-native applications on your unified data. Start with Building Applications on MemberJunction — the developer’s hub that walks the schema-to-app model and links every layer — and the framework comparison vs. Next.js/Vercel, Supabase, Rails, and Django.

// 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' })
});
