React does detect and warn you about mismatches in dev mode. It can be tricky to track down if it only happens in prod, though (due to different data – like start/end times for content coming from a CMS).
React could do better in both dev and prod though, IMO. It doesn't tell you where/which component had the issue, just the type of DOM node with a mismatch.
