## Which SDK Should I Use?

<CardGroup cols={3}>
  <Card title="Use Python if…" icon="python" color="#3776AB">
    You're building backend automation, data pipelines, or scripts. Best for compliance
    engineers who want to process and analyse regulatory data programmatically.
  </Card>

  <Card title="Use TypeScript if…" icon="js" color="#3178C6">
    You're building Node.js APIs, serverless functions, or browser-side tools. Best when
    you need async operations and strong type safety.
  </Card>

  <Card title="Use PHP if…" icon="php" color="#777BB4">
    You're working in a Laravel, Symfony, or WordPress application. The PHP SDK integrates
    directly into Composer-based projects with no extra setup.
  </Card>

  <Card title="Use Java if…" icon="java" color="#E76F00">
    You're building JVM-based services, Spring Boot applications, or enterprise backend
    systems. The Java SDK uses only stdlib — no external dependencies required.
  </Card>

  <Card title="Use Flutter if…" icon="mobile" color="#02569B">
    You're building a mobile, desktop, or web Flutter app, or a Dart CLI tool. The only
    SDK with full Flutter Web compatibility and Stream-based auto-pagination.
  </Card>

  <Card title="Use Rust if…" icon="rust" color="#CE422B">
    You're building high-performance backend services, CLI tools, or systems software where
    memory safety and zero-cost abstractions matter. Best for latency-critical applications
    that need async Tokio runtimes and compile-time type guarantees.
  </Card>

## Supported Frameworks

All 19 EU regulatory frameworks are available across every SDK — from GDPR and CRA to
the AI Act, DORA, NIS2, and beyond.
