I don't know of anything that is working yet, but I know some people working on it (intentionally vague).

Roman law, on which the legal systems of Germany, most of Europe, Turkey etc. are based relies more heavily on statutes than Anglo-American case law, but cases do play a role there, too. That's why a practically useful system also needs to have access to court decisions, commentary etc. - and while the statues are in the public domain, a lot of the other knowledge is owned by specialist publishers (such as: C.H. Beck, Nomos, Mohr Siebeck, De Gruyter, Otto Schmidt, C.F. Müller, Manz, Verlag Österreich, Schulthess, Stämpfli, Dalloz, LexisNexis, Lefebvre Dalloz, Giuffrè Francis Lefebvre, CEDAM, Giappichelli, Il Mulino, Aranzadi, Tirant lo Blanch, Marcial Pons, Dykinson, Tecnos, Lefebvre, Almedina, Gestlegal, AAFDL, Kluwer, Boom juridisch, Wolters Kluwer, Larcier-Intersentia, Anthemis, Sakkoulas, Nomiki Bibliothiki, Universul Juridic, Hamangiu).

Internationally, legal systems appear to undergo a sort of convergence, which means statutes increasingly matter in the U.S. and cases increasingly matter in European law (according to a law partner friend).
