or: rails /reɪlz/

Ruby on Rails is most commonly pronounced "ruby on rails" (/ˌruːbi ɑːn ˈreɪlz/). This is the widely-used reading among engineers, though edge cases exist.

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will. Pronounce is a community-maintained dictionary — every entry tagged with a confidence level and (where possible) a citable source.
