### PostHog LLM Analytics Integration - Integrate PostHog analytics into any LLM application using provider-specific guides or the manual capture fallback for custom setups. - Capture essential metrics including input/output tokens, model names, latency, and costs while ensuring PII is never sent in events. - Use the instance-based Posthog() constructor, enable exception autocapture, and call shutdown() to ensure all events are flushed.

### PostHog Log Ingestion for Other Languages - Configure OTLP exporters to send logs directly to PostHog's ingestion endpoint using the OpenTelemetry protocol. - Use environment variables for all sensitive configuration, including PostHog project keys and OTLP endpoints. - Implement structured logging with key-value pairs to enhance searchability without replacing existing application logging logic.

### PostHog Python Integration - Install the posthog package and initialize the Posthog() class with enable_exception_autocapture=True for automatic error tracking. - Use environment variables for API keys and register posthog_client.shutdown with atexit to ensure all events are flushed on exit. - Identify users via set() for person properties and never include PII like emails or names within capture() event properties.

### Analyzing Experiment Session Replays - Retrieve experiment metadata and variant keys from the feature flag to ensure accurate filtering for each test group. - Construct session recording filters using the $feature_flag_called event and the specific $feature/<flag_key> property for each variant. - Compare session duration, activity metrics, and navigation paths across variants to provide qualitative insights on user behavior.

### PostHog Ruby Integration - Install the posthog-ruby gem and initialize the client using environment variables for API keys and host configuration. - Use client.capture and client.identify with hash arguments, but use positional arguments for client.capture_exception. - Ensure client.shutdown is called before script exit to prevent event loss, ideally within an ensure block for proper cleanup.

### PostHog Integration for Nuxt 3.6 - Follow the four-step setup workflow to initialize PostHog analytics within your Nuxt 3.0 to 3.6 application. - Use environment variables for all PostHog keys and maintain consistency by following the provided example project patterns. - Identify users during authentication events and use specific headers to correlate client-side sessions with backend requests.

### PostHog Integration for React Router v7 - Implement PostHog analytics using the declarative pattern by following the four-step setup workflow and referencing the example project. - Use environment variables for API keys and trigger analytics capture directly within event handlers rather than inside useEffect hooks. - Identify users during authentication and maintain session correlation by passing distinct IDs via headers for backend-integrated flows.

### PostHog Android Integration - Initialize PostHog in the Application class onCreate method using environment variables for keys to ensure secure, early configuration. - Follow the provided example project patterns and ensure every activity includes an android:label for accurate screen view tracking. - Identify users during login and signup, passing session and distinct ID headers to maintain correlation across frontend and backend.

### PostHog Django Integration - Install the posthog package and initialize the client in AppConfig.ready() using environment variables for API keys and host settings. - Add PosthogContextMiddleware to your Django middleware and use the instance-based Posthog() constructor with exception autocapture. - Use set() or identify_context() for user identification, ensuring PII is excluded from capture() event properties to maintain privacy.
