Why App Builder?

Bridging the gap between design, development, and business, our low-code platform fosters collaboration and accelerates app-building cycles, reducing development time by 80%. As a leading OutSystems alternative, App Builder empowers organizations and teams with pixel-perfect code generation, an extensive toolbox, and AI capabilities so they can build and drive innovation with the right tools. No limitations or hidden costs.

Blazing Fast Grids & Charts

  • Unlike OutSystems, where working with high-volume data and user interactions often requires additional development effort, we make this process effortless.

  • App Builder provides a robust library of 65+ UI components for large datasets and complex visualizations.

  • Easily drag and drop the controls you need directly to the canvas in a complete WYSIWYG app-building experience.

Low-Code WYSIWYG Drag & Drop Tool

Build With Low-Code Simplicity. Amplify With AI.

  • Anything you craft with App Builder has the look and feel of a professionally designed enterprise-grade app without requiring a design team.

  • Leverage AI-driven features to easily generate views or images based on plain language prompts.

  • Match any branding requirement with various theming and styling options—no clunky visual editing involved.

You Have Full Control Over Your App

  • Developers’ major concern when using low-code tools is limited control over generated code or apps’ functionality. However, with App Builder, you can achieve developer freedom and refine UX.

  • You can apply customizations, create color palettes for charts, change themes, preview and generate clean, production-ready code, publish to GitHub, or download a zip.

  • There’s no vendor lock-in.

The Ultimate Design-To-Code Story

  • Convert Figma designs to code instantly.

  • Eliminate error-prone hand coding and designer-developer handoffs.

Superior Integration & Cross-Platform Accessibility
