# SDKs

> Native Freeplay SDKs for Python, TypeScript, and Java/Kotlin.

Freeplay provides native SDKs for the most popular development languages. Each SDK offers the same core functionality with language-idiomatic interfaces.

<Tip>
  Using Claude Code or Cursor? Check out the experimental [Freeplay MCP server, skills, and plugin](/developer-resources/overview#claude-code--mcp-integration) to interact with Freeplay directly from your editor through natural language.

* **Observability**: Record sessions, traces, and completions automatically
* **Testing**: Create and execute test runs programmatically
* **Feedback**: Capture customer feedback on completions and traces

## SDK vs Framework Integrations

If you're using LangGraph, Vercel AI SDK, Google ADK, or other AI frameworks that emit clean OTel traces, consider our framework integrations or [Open Telemetry (OTel)](/developer-resources/integrations/tracing-with-otel) for automatic observability with minimal code changes.
