MDN/Archives/Projects/Development/CompatibilityTables

Web compatibility tables (WCT) are one of the key feature of MDN. It allows users to know more about the reliability of any web standard features and to ease the use of web technologies. Currently, the data are gather and maintain "by hand". Thanks to our awesome community we have some good data. However, this is hardly sustainable as the number of technologies is growing as well a the complexity of the implementation. We start to face some difficulties to stay up to date and to provide and improved content around those data.
