Renderer-independent by design

Describe a visualization once. Render it where you need it.

Think of the experimental Graphics Server Protocol (GSP) as a common language between scientific Python code and rendering engines. Your code describes points, images, axes, layouts, and interactions. GSP passes that description to Datoviz, Matplotlib, or another backend to draw it.

One scientific graphics stack

From scientific plots to interactive 3D worlds.

These examples are rendered by Datoviz, the GPU engine planned underneath VisPy 2. They show the same foundations at work in precise plotting, geographic data, physical simulation, and volumetric science.

Built for many fields

Reusable building blocks for specialized science.

Different fields need views and interactions designed for their data. VisPy aims to support community-built components for neuroscience, geoscience, astronomy, microscopy, molecular biology, medical imaging, climate science, engineering, and many other disciplines.

Continuity and renewal

Founded in 2013, VisPy grew into a widely used open-source GPU library. Its next chapter keeps that community and experience while adding modern rendering, multiple output formats, and support for complete scientific tools.

Open development, sustained support

VisPy is a NumFOCUS affiliated project. Its development has been supported by the Chan Zuckerberg Initiative and contributors across the scientific Python community.
