Not a complete list of every feature and language, but WALS [0] would probably be of interest to you. It has a decent list of language features you can browse and read about, shows you a map with the occurrence of each feature with languages placed on that map for each feature, and lists which languages have each feature (to the extent that is recorded in that particular database).
