Which site running Rails has the most traffic? That was the question the 2008 version of this index asked, seeded from the rails100 wiki. This one keeps all 103 of those original entries, dead ones included, and adds every Rails site HTTP Archive still detects in the CrUX top 50,000, plus the Rails Foundation's members. Rails detection is a guess made by a crawler, and sites move off Rails without telling anyone, so treat the membership as good-faith rather than gospel.
