178 name collisions covering 356 distinct gems, out of 195399 on RubyGems.org.
These are separate gems that fold to the same name, so any tool storing one gem per file on a case-insensitive filesystem (macOS APFS, Windows) will have them overwrite each other.
Newest release among any colliding gem: 2026-07-20 — several of these gems are still actively maintained.
