# Welcome to the Stacksync Developer Platform

The Stacksync Developer Platform lets you build and deploy connectors that extend Stacksync with new capabilities. With Workflow Connectors, you can add actions and triggers to workflows and connect Stacksync to internal systems, proprietary applications, and third-party APIs. Once deployed, a connector becomes available in your Stacksync workspace and can be used alongside native Stacksync connectors.

:point\_right: If you are new to the Stacksync developer platform, start here to [build your first workflow connector in a guided tutorial](/developers/getting-started-with-stacksync-cli/quickstart.md).

### Stacksync CLI

The Stacksync CLI is the primary development tool for creating, testing, and deploying resources on the Stacksync Developer Platform. From your terminal, you can initialize a project, run it locally, validate its configuration, and deploy it to your workspace.

Today, the CLI is used to build Workflow Connectors and is designed to support additional Stacksync resources over time.

### Connector Development Kit

The Connector Development Kit (CDK) is the framework for building Workflow Connectors. It provides the interfaces, components, and building blocks used to implement authentication, modules, inputs, outputs, and execution logic.

The CLI generates the project structure, while the CDK provides the APIs used to build the connector. Together, they provide a consistent development experience and ensure connectors integrate seamlessly with Stacksync.

### Build Your First Workflow Connector

Follow the guided workflow to create, develop, test, and deploy your first Workflow Connector. The generated project includes built-in documentation that explains its structure and can be followed directly or used with an AI coding assistant.
