Programming Without Coding Technology 2.0

Program Visually.
Think Creatively.

PWCT2 is a self-hosting visual programming language that lets you build applications and 2D games through interactive visualization — powered by the Ring programming language.

PWCT2 Game Development

General-Purpose Visual
Programming Language

PWCT has been introducing innovative concepts over two decades that redefine how developers interact with code — replacing traditional approaches with more intuitive visual methods.

🔄

Graphical Code
Replacement

GCR replaces traditional drag-and-drop with automatic Steps Tree generation. The system blends diagrammatic and form-based programming through seamless automatic visual representation.

⏱️

Time Dimension
Integration

PWCT integrates the time dimension at the program design level. Play your programs as movies to visualize step-by-step implementation and travel back through your design history.

🏗️

Self-Hosting
Architecture

PWCT2 is built with PWCT2. As a self-hosting visual programming language, it validates its own capabilities by being its own most demanding application.

Everything You Need to Build

Whether you're a beginner learning programming concepts or a professional Ring developer seeking productivity — PWCT2 adapts to your workflow.

01

Goal Designer

Visual programming using the Steps Editor instead of a traditional code editor. Browse components visually and build your logic step by step.

Visual Programming
02

Form Designer

Design your application's user interface with a WYSIWYG form designer. Drag, resize, and customize GUI elements visually.

WYSIWYG
03

Time Machine

Play programs as a movie and run programs in the past. Navigate through your program's design timeline with a slider control.

Unique Feature
04

Interactive Visualization

Import textual source code and instantly see the interactive visual representation. Understand any Ring program through its visual structure.

05

Rich Comments

Add images, tables, and rich media to your application design. Make your programs self-documenting and visually informative.
