WPT Connect to W3C Public IRC. Test suites for Web platform specs — including WHATWG, W3C, and others. The web-platform-tests Project is a W3C-coordinated attempt to build a cross-browser testsuite for the Web-platform stack. Writing tests in a way that allows them to be run in all browsers gives browser projects confidence that they are shipping software that is compatible with other implementations, and that later implementations will be compatible with their implementations.
Itty-bitty is a tool to create links that contain small sites. itty.bitty takes html (or other data), compresses it into a URL fragment, and provides a link that can be shared. When it is opened, it inflates that data on the receiver’s side.
