Defold compiles its native engine core to WebAssembly and packages your project as an HTML5 build, producing a relatively small, fast-loading web export. You build for the HTML5 target in the Defold editor, test in a browser, then publish to a game portal or through an SDK that adapts the build to multiple platforms.<\/strong><\/p>\n

Defold’s engine core is written in C\/C++ and compiles down to WebAssembly, with the rest of the project packaged as a standard HTML5 build. Because the runtime is small and compiled rather than interpreted, Defold web exports tend to load fast and run efficiently in the browser, which matters for casual and hyper-casual games where every second of load time affects retention. You build the HTML5 target from the Defold editor, then test it directly in a browser before shipping.<\/p>\n

Once the build works locally, the next step is choosing where it runs. If you want the same build to reach many portals without rewriting platform code for each one, Playgama Bridge<\/a> is an open-source SDK with a Defold plugin that adapts one HTML5 build to many platforms, including ads and in-app purchases where a platform supports them.<\/p>\n

Where can you publish a Defold HTML5 build?<\/h2>\n
