What's Missing

Municipal/city services, voting/elections admin, social services, immigration, public transit, emergency management, most G20 nations.

The Bottom Line

Rating: 4/5 — Institutional adoption by five government agencies is remarkable for a protocol this young. Legislative and procurement coverage is comprehensive. The 188-tool US government server alone justifies the category. International coverage beyond US/France/India is thin.
