## Not Sure Which to Choose?

<AccordionGroup>
  <Accordion title="I want to track server-side events" icon="server">
    **Choose Backend APIs** if you want to:

    * Track events from your server/API
    * Handle webhooks and background processing
    * Ensure reliable event delivery
    * Track events that don't depend on user's browser

    Examples: user registration, subscription changes, payment events, admin actions.
  </Accordion>

  <Accordion title="I have a mobile app" icon="mobile">
    **Choose Mobile Apps** if you're building:

    * React Native applications
    * Flutter applications
    * Native iOS/Android apps (use REST API)

    Mobile SDKs provide better performance and platform-specific features.
  </Accordion>

  <Accordion title="I have a web application" icon="globe">
    **Choose Web Apps** if you're building:

    * React, Vue, Angular applications
    * Next.js, Nuxt.js applications
    * Static websites with JavaScript
    * Any frontend that runs in a browser

    Perfect for tracking user interactions, page views, and real-time behavior.
  </Accordion>

  <Accordion title="I want to use multiple methods" icon="layers">
    **You can combine approaches!** Many applications use:

    * **Backend APIs** for server events (signups, payments)
    * **Web Apps** for user interactions (clicks, page views)
    * **Mobile Apps** for mobile-specific tracking

    All methods send events to the same UserBoost dashboard.
  </Accordion>
