This Error Message is due to WebGL. So first let us get to know about WebGL.

What is WebGL?

Web Graphics Library also known as the “WebGL” is a Javascript API which Renders interactive 3D computer graphics and Graphics(2D) on any web browser that is Compatible without needing any plug-ins or add-ons.

The Computer’s GPU or also known as Graphics Processing Unit helps the execution of the Javascript which has all the webGL program Codes.


The Group popularly known as the “Khronos Group designs and maintains WebGL, and it is a non-profit group, situated in Beaverton, Oregon (USA).

Usage of WebGL

WebGL acts as a thin sheet of cloth around OpenGL which is a used for drawing 2D graphics (Low-Level Library). It helps in pushing data to the GPU, and execution of the specialized code on the GPU itself.

WebGL is the easy and best way to bring 3D graphics and also 2D everywhere. Once written, it can run Everywhere.


WebGL apart from used in 3D wed design and gaming, it also has amazed scientists for research and scientific works.A book named “Cellular Automata” have used this technology to simulate Debris flow.


Did you know? NASA, Yes “NASA” developed an interactive web application called experience curiosity to celebrate the 3rd anniversary of the famous Curiosity rover landing on Mars.

How to Fix Rats! WebGL Hit A Snag

Sometimes when using WebGL we have an error about site crashing and telling us that WebGL is not supported. You will come across an error message saying “Rats! WebGL hit a snag” while surfing on Chrome browser.
