HTML5test.com is a discontinued[3]web app for evaluating aweb browser's implementation some of commonweb standards, includingHTML5,Web SQL Database,Scalable Vector Graphics (SVG), andWebGL.[4][1]
The test suite was developed by Dutch web programmer Niels Leenheer and published in March 2010.[5] The app returns an integer score out of a possible 555 points. The point total has changed multiple times over the software's evolution. Leenheer introduced the present scoring system as part of a major redesign of the test introduced in November 2013.[6] On 9 January 2024, Leenheer announced a problem with the app's server and added that he has no incentives to work on it anymore.[3] Since then third-party mirrors have been set up athtml5test
HTML5Test.com evaluates the browser's support forWeb storage, theW3C Geolocation API, HTML5-specificHTML elements (including thecanvas element), and other features.[7][8] It does not evaluate a browser's conformance to other web standards, such asCascading Style Sheets,ECMAScript, or theDocument Object Model. Conformance testing for those standards is within the purview ofAcid3, an automated test published byIan Hickson in 2008.[9] Similarly, Acid3 does not evaluate a browser's HTML5 conformance. The test scope of HTML5Test.com and that of Acid3 are mutually exclusive.
