A cross-platform framework for building powerful, fast, elegant 2D and 3D apps
CODE ONCE, RUN EVERYWHERE (CORE)
With Cogent Core, you can write your app once and it will instantly run on macOS, Windows, Linux, iOS, Android, and the web, automatically scaling to any screen. Instead of struggling with platform-specific code in a multitude of languages, you can easily write and maintain a single Go codebase.
EFFORTLESS ELEGANCE
Cogent Core is built on Go, a high-level language designed for building elegant, readable, and scalable code with full type safety and a robust design that never gets in your way. Cogent Core makes it easy to get started with cross-platform app development in just two commands and seven lines of simple code.
COMPLETELY CUSTOMIZABLE
Cogent Core allows developers and users to fully customize apps to fit their unique needs and preferences through a robust styling system and a powerful color system that allow developers and users to instantly customize every aspect of the appearance and behavior of an app.
POWERFUL FEATURES
Cogent Core comes with a powerful set of advanced features that allow you to make almost anything, including fully featured text editors, video and audio players, interactive 3D graphics, customizable data plots, Markdown and HTML rendering, SVG and canvas vector graphics, and automatic views of any Go data structure for instant data binding and advanced app inspection.
OPTIMIZED EXPERIENCE
Every part of your development experience is guided by a comprehensive set of editable interactive example-based documentation, in-depth video tutorials, easy-to-use command line tools specialized for Cogent Core, and active support and development from the Cogent Core developers.
EXTREMELY FAST
Cogent Core is powered by WebGPU, a modern, cross-platform, high-performance graphics framework that allows apps to run on all platforms at extremely fast speeds. All Cogent Core apps compile to machine code, allowing them to run without any overhead.
FREE AND OPEN SOURCE
Cogent Core is completely free and open source under the permissive BSD-3 License, allowing you to use Cogent Core for any purpose, commercially or personally. We believe that software works best when everyone can use it.
USED AROUND THE WORLD

Why Cogent Core instead of something else?
THE PROBLEM
After using other frameworks built on HTML and Qt for years to make apps ranging from simple tools to complex scientific models, we realized that we were spending more time dealing with excessive boilerplate, browser inconsistencies, and dependency management issues than actual app development.
THE SOLUTION
We decided to make a framework that would allow us to focus on app content and logic by providing a consistent and elegant API that automatically handles cross-platform support, user customization, and app packaging and deployment.
THE RESULT
Instead of constantly jumping through hoops to create a consistent, easy-to-use, cross-platform app, you can now take advantage of a powerful featureset on all platforms and vastly simplify your development experience.
