UK cross-platform technology company Turbulenz has open-sourced its engine.

Based on HTML5 and WebGL, it's a modular browser-based engine for 2D and 3D games

For example, it's been used by Denki for Save the Day and by Wonderstruck for Polycraft.

"We've had a lot of interest in the Turbulenz Engine via our SDK packages and many of the people who try it out have praised the features and performance. However, two issues that have often come up are any sort of restrictive licensing and the ease of getting things started," the company said in a statement.

"By releasing the Turbulenz Engine as open source under a standard liberal MIT license we hope to ease the adoption costs and ensure that people don't feel in any way restricted by using the Engine."
