    • Creator Studio: Enables process owners and line of business users to build no-code request-fulfillment apps quickly, such as forms for approvals.
    • App Engine Studio: Allows citizen developers to create a wider range of low-code applications with guided templates and holistic development experience.
    • ServiceNow Studio: Provides platform and citizen developers a unified, modern environment with integrated low-code tools, streamlined navigation, and built-in tracking for faster app delivery.
    • ServiceNow IDE and SDK: Designed for source code developers to build and maintain applications using JavaScript and ServiceNow Fluent, leveraging Visual Studio Code environments with conversational AI assistance through Build Agent.

    AI Capabilities in Application Development

    AI features enhance app development efficiency and creativity:

    • Now Assist in ServiceNow Studio: Enables app creation through conversational interaction, refining app design dynamically.
    • App Summarization: Quickly reviews and summarizes app contents for better understanding and documentation.
    • Now Assist for App Engine: Integrates AI agents and skills to extend low-code applications.
    • AI-Powered Code Generation: Generates scripts from text or code snippets, accelerating scripting tasks.

    Building No-Code and Low-Code Applications

    ServiceNow facilitates rapid app development with governance and scalability:

    • No-Code with Creator Studio: Build simple request-fulfillment applications without coding.
    • Low-Code with App Engine Studio: Accelerate innovation with guided templates, process automation, mobile-first design, and governance controls to manage compliance and scaling.

    Developing Pro-Code Applications

    For advanced developers, ServiceNow Studio and IDE offer:

    • Fine-grained control over coding, debugging, source control integration (Git), and deployment.
    • Support for team collaboration through role-based access to application resources.
    • Developer Sandboxes for isolated, parallel development to reduce conflicts and speed up production.

    Builder Library

    The Builder Library provides specialized tools for different development needs, such as Decision Builder, UI Builder, and Workspace Builder, enabling customers to select appropriate builders for their specific application requirements.

    Build a custom application to meet the business needs of your organization. Choose a builder for the type of user experience or workflow that you want to create.

    Which app builder should I use?

    Use the following table to choose the app building experience that matches your role and technical background.

    Table 1. App builders
    Tool Users Features
    Creator Studio: Build an app without code. Process owners, line of business owners Build request-fulfillment apps without writing code.

    For example, create an application to request office supplies: a user fills out a form, and an approver accepts or denies the request. For more information, see Exploring Creator Studio.
    App Engine Studio: Build a range of apps using low-code tools. Citizen developers Build a broader range of apps than Creator Studio without writing code.

    For more information, see Exploring App Engine Studio.
    ServiceNow Studio: Build and deliver apps in a unified environment. Citizen developers, Platform developers Build apps in a unified development environment.

    ServiceNow Studio provides streamlined navigation, integrated low-code tools, and built-in tracking and packaging so you can develop and ship apps faster.

    For more information, see Exploring ServiceNow Studio.
    ServiceNow IDE and ServiceNow SDK: Build apps in source code. Source code developers Develop applications in source code with ServiceNow Fluent, create JavaScript modules, and use third-party libraries. ServiceNow Fluent is a domain-specific programming language for creating application metadata in code. Use Build Agent in ServiceNow IDE to create and update apps in source code with a conversational interaction.

    The ServiceNow IDE runs Visual Studio Code for the Web on the ServiceNow AI Platform. The ServiceNow SDK runs Visual Studio Code Desktop locally. For more information, see Building applications in source code.
