What is FLXBL?

FLXBL combines the power of PostgreSQL for schema management with Neo4j for graph data storage. When you define a schema, FLXBL automatically:

  • Generates REST API endpoints for all CRUD operations
  • Creates a GraphQL API with queries and mutations
  • Handles relationships between entities as graph edges
  • Manages schema versioning and migrations
  • Provides multi-tenant isolation

Key Features

Schema-First Development

Define your entities and relationships once. FLXBL generates type-safe APIs, OpenAPI specs, and GraphQL schemas automatically.

MCP Tool Integration

Use the FLXBL MCP server with Cursor, Windsurf, or any MCP-compatible IDE. Design schemas through natural language conversation with AI assistants.

Powerful Query DSL

Query your data with a JSON-based DSL that supports MongoDB-style operators and graph traversal. No SQL or Cypher knowledge required.

Enterprise Ready

Built-in multi-tenancy, role-based access control, scoped API keys, webhooks, and rate limiting. Deploy self-hosted or use our managed service.
