Everything you need to go from script to app.

Apleno Designer removes every front-end obstacle between your data logic and your end users.

WYSIWYG UI builder

Assemble professional interfaces from a rich widget library: charts, tables, forms, maps, KPI cards and more. What you design is exactly what your users see.

Drag-and-drop layout, responsive grids, real-time property editing. No HTML or CSS required.

Visual workflow editor

Define your application as a visual graph of UI screens, script steps, conditions, and transitions. Apleno Designer builds the full runtime from your diagram.

Complex branching, dynamic routing based on user input.

R & Python runtime

Each script step runs in your configured environment. Scripts receive the full app state and can update any widget, navigate any screen, or trigger any action.

Works with renv, venv, and conda. Full package access.

Live preview in VS Code

Click Run and your app opens instantly inside the editor. Interact with it, debug it, and iterate without switching context or deploying anywhere.

Powered by an embedded app server.

Low-code, not no-code

Apleno Designer is made for people who can write a script but don’t want to write a web application. You control your logic and Apleno handles everything around it.

Full programmatic access to every widget property. Escape hatches for power users.
