Open & Extensible
Low-Code Development

Go beyond the low-code status quo with the interoperable Mendix platform

Develop applications without limits

The Mendix low-code application development platform is built on open standards and open-source technologies, giving developers unlimited opportunities to extend platform and application capabilities.

Seamlessly integrate the platform with your tech stack, extend applications with custom code, leverage open APIs to programmatically adjust models, and build beyond the standard expectations of low-code. Mendix is open and extensible at every level.

Get started

Platform extensibility

Adapt the Mendix platform to your enterprise development needs

  • Platform

    The core functionality of the Mendix platform is accessible through APIs. Developers can connect Mendix with existing technologies, incorporate third-party testing services, or use automation services (such as Jenkins or GitLab) to orchestrate a CI/CD pipeline.

    • Integrate Mendix with third-party systems and applications
    • Connect Mendix to your existing CI/CD pipeline
    • Create application projects
    • Manage sprints, stories, user feedback, permissions, and security
    • Automate the migration of applications to other platforms with the Mendix Platform SDK
  • Models

    With the Mendix Model SDK, developers can access the core of every Mendix application, including: microflows, custom widgets, security constraints, Java actions, and more. We ensure these models are fully open, accessible, and shareable.

    • Migrate legacy applications to the cloud
    • Read, modify, and analyze the model of any application
    • Choose how you migrate applications to and from Mendix

"When integrations are required, Mendix is preferred."

Application extensibility

Extend the capabilities of your applications with reusable components and custom code

  • Front-end

    Developers can extend the front-end capabilities of every application using custom-built widgets and actions leveraging Javascript. Mendix empowers developers to use open frameworks like React Native, PWA, and Mendix’s Atlas UI to build engaging web and mobile application experiences.

    • Leveraging the Mendix Client Javascript library to connect to data, logic, and pages modeled in your Mendix IDE
    • Use existing open-sourced libraries with tools such as Node Package Manager (NPM)
    • Incorporate third-party React Native components to enhance the UX for native mobile applications
  • Integrations

    Integrate Mendix with your ecosystem of third-party software tools and technology with support for REST, SOAP, GraphQL, and JDBC. Developers work more efficiently in Mendix by easily accessing and exposing information in your existing application portfolio.

    • Unlock and govern low-code data integration with Mendix Connect
    • Easily leverage open standards and third-party services within your Mendix applications
    • Expose live Mendix application data in one click for consumption in BI tools like Tableau, analytics platforms like SAS and R, or in Excel with Mendix OData support
  • Runtime

    The Mendix Runtime is implemented using Scala and Java and runs on the Java Virtual Machine (JVM), which gives you portability across environments. Developers can use custom Java/Scala code to extend the possibilities of the Mendix Runtime.

    • Extend the Platform’s runtime capabilities with Java actions
    • Leverage existing Java/Scala libraries in your applications
    • Use tools like Maven and Gradle to control your dependencies
  • Cloud

    Mendix is cloud-native by default, and applications are containerized, portable, and resilient out of the box. With our multi-cloud capabilities, developers have the freedom to deploys applications on their own terms, backed by the support of our high availability, robust security, and unmatched reliability.

  • What is the difference between an open and closed platform?

    An open application development platform provides accessible APIs and enables developers to connect with third-party systems. All open-source platforms are considered open, but not all open platforms are open-source.

    A closed platform can be customized, but only by developers with proprietary knowledge and capabilities. Closed platforms have more restrictions, including difficulty integrating with third-party tools.

  • How can the extensibility of a platform benefit a business?

    Open and extensible application development platforms are beneficial for every enterprise. By extending a low-code platform to fit business and development needs, enterprises are able to adapt and respond swiftly to disruptions and changing requirements.

    Developers are empowered to build new functionalities, extend capabilities, and integrate with third-party tools, opening up a limitless world of possibilities for your organization.
