Choosing the Right SDK

1

Client-side vs Server-side

Use client-side SDKs (JavaScript, React, Mobile) for user-facing applications where you want autocapture, session replay, and real-time user tracking.Use server-side SDKs (Python, Node, Ruby) for backend services, API endpoints, scheduled jobs, or when you need more control over what data is sent.
2

Framework-specific vs Generic

Choose framework-specific SDKs (React, Next.js, Django) when available for better integration with your framework’s patterns and conventions.Use generic SDKs (JavaScript, Python, Node) for vanilla applications or when a framework-specific option doesn’t exist.
