Phaser is an exciting, free, and rapid open-source HTML5 game development framework that supports WebGL and Canvas rendering across both desktop and mobile web browsers. With over a decade of active development, Phaser prioritizes web standards and places the browser experience at the forefront of its design. For Phaser, exporting to the web is not just a secondary feature; it is the primary focus. The framework is completely open-source, granting users full access to each line of code within its core library. Boasting a larger selection of pre-made templates than any competing game framework, Phaser also serves as an excellent command-line interface (CLI) tool. Games created with Phaser have been integral to various marketing initiatives for many years, finding applications in numerous settings, including major Hollywood film promotions, extensive brand campaigns, educational materials, interactive experiences, television programs, news segments, charity events, and live marketing events. Additionally, the versatility and accessibility of Phaser make it a popular choice for both novice and experienced developers alike.
