Due to the ongoing consolidation of the gaming ecosystem at Facebook, we have introduced important changes to the Web Games on Facebook and Facebook Gameroom platforms that might affect your games. To learn more read our blog post.
Here's an overview on different web technologies supported by browsers and available for game developers today:
Supported by almost all browsers today, and without requiring any plug-ins to install, we recommend HTML5 (WebGL) technology for developers to get started with today. We have a list of HTML5 engines, Cross-Platform Engines, Toolkits and Libraries, or the Facebook-Unity WebGL option.
On another note, Facebook Gameroom has built-in support for Web Games built in Flash, working independently from the browser announcements listed on this page. Players will be able to continue playing their games in Facebook Gameroom.
Adobe and major web browsers plan to discontinue support for the Flash Player by the end of this year. It also means that Adobe will not issue Flash Player updates or security patches after the end of life date. Therefore, as of January 1, 2021, web browsers will no longer render Flash content, and any website serving it will therefore leave people with a broken experience. This also applies to web games on Facebook.com - any game using Flash after 1/1/2021 will no longer be playable. To learn more read our blog post.
On 25 Oct, we ran a webinar Migrating from Flash to HTML5 for developers who are interested to port their existing Flash titles to HTML5 technology. To rewatch this webinar, you can click the video link below:
