What is a Temporal SDK?

A Temporal SDK is a language-specific library that offers APIs to do the following:

1. Construct and use a Temporal Client
2. Develop Workflow Definitions
3. Develop Worker Programs

A Temporal SDK enables you to write your application code using the full power of the programming language, while the Temporal Platform handles the durability, reliability, and scalability of the application.

Temporal currently offers the following SDKs:

• Get started with the Go SDK
• Get started with the Java SDK
• Get started with the PHP SDK
• Get started with the Python SDK
• How to use the TypeScript SDK

Each SDK emits metrics which can be ingested into monitoring platforms. See the SDK metrics reference for a complete list.
