ServiceNow Fluent is a domain-specific programming language for creating application metadata in code. The ServiceNow IDE is an implementation of Visual Studio Code for the Web on the ServiceNow AI Platform. The ServiceNow SDK uses Visual Studio Code Desktop locally. For more information, see [Building applications in source code](https://www.servicenow.com/docs/gjFgQZz3ZfxdXU0DH4e5MQ "Create and develop custom applications in source code using familiar development tools and processes."). **Are you a developer who wants more control in a centralized user interface?** Build apps smarter and deliver them faster with the new ServiceNow Studio. ServiceNow Studio empowers platform developers with a modern, unified environment for building on the ServiceNow AI Platform. ServiceNow Studio features streamlined navigation to applications and metadata, integrated low-code tools, efficient tracking and packaging of development work that accelerates development processes and enhances productivity. For more information, see [Exploring ServiceNow Studio](https://www.servicenow.com/docs/TAxFckGJZQA63l61AAeplw "ServiceNow Studio delivers a cohesive, efficient experience for mid-to-high-skilled developers to create, modify, and extend apps. ServiceNow Studio is a single place that you can go to do development work, delivering value to your business faster."). **Need a more general app but still want low-code options?** App Engine Studio lets you build a broader range of apps than Creator Studio without being a programming pro. For more information, see [Exploring App Engine Studio](https://www.servicenow.com/docs/GsErco9kNjmVSnc7uuStNw "Learn how you can use the low-code app development tool, App Engine Studio (AES), to build powerful applications using guided setup, predefined templates, and workflows."). **Want to build an app easily, without code?** Creator Studio specializes in helping you craft request-fulfillment applications without writing code. For example, an application to request office supplies by filling out a form, and someone approves or denies your request. For more information, see [Exploring Creator Studio](https://www.servicenow.com/docs/KJj4Hq8nocCGn1DU21Q92A "Creator Studio makes creating apps easier by dividing their creation into simple steps. In this section, we'll explain each one."). ## Troubleshoot and get help {#servicenow-sdk-landing__section_c22_5d1_jbc} * To learn more about what's new in the Xanadu release, see the [ServiceNow SDK release notes](https://www.servicenow.com/docs/access?context=servicenow-sdk-rn&version=xanadu&pubname=xanadu-release-notes&ft:locale=en-US). * [ServiceNow SDK and Fluent Creator Toolbox](https://www.youtube.com/live/PHFZBsbTTtI?si=DbZq3aTEtqUlxpbi&t=2167) video * [ServiceNow SDK examples](https://github.com/ServiceNow/sdk-examples) GitHub repository * [ServiceNow IDE, SDK, and Fluent forum](https://www.servicenow.com/community/servicenow-ide-sdk-and-fluent/bd-p/ide-sdk-fluent-forum) in the ServiceNow Community * [ServiceNow IDE, SDK, and Fluent articles](https://www.servicenow.com/community/servicenow-ide-sdk-and-fluent/tkb-p/ide-sdk-fluent-articles) in the ServiceNow Community * [Search the Known Error Portal for known error articles](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0597477) * [Contact Customer Service and Support](https://support.servicenow.com/now?draw=case) {#servicenow-sdk-landing__ul_d22_5d1_jbc} **Related concepts** * [ServiceNow Fluent](https://www.servicenow.com/docs/e_U08PErXJdneo77q8TISQ "Define application metadata in source code using the ServiceNow Fluent domain-specific programming language.") * [JavaScript modules and third-party libraries](https://www.servicenow.com/docs/~hgNIdknFEpmBqpxVylH0A "Optimize your code base using JavaScript modules to group related code or add third-party libraries and reuse their code within applications.")
