Vapi is most commonly pronounced "vappy" (/ˈvæpi/). This is the widely-used reading among engineers, though edge cases exist.
Vapi (YC W21, vapi.ai) is a developer platform for building voice AI agents; co-founded by Jordan Dearsley (CEO) and Nikhil Gupta (CTO) — not a single founder. The name compresses "Voice API" (every feature is accessible via its API), confirmed by multiple sources. Stress falls on the FIRST syllable with a short /æ/: VAP-ee, rhyming with "happy" (/ˈvæpi/); corroborated by HowToPronounce (/vˈæ.pi/, "va-pee"). No official creator pronunciation statement was found, so confidence stays community-consensus. Non-native devs often default to "VAH-pee" (/ˈvɑpi/) or "VAY-pie" (/ˈveɪpaɪ/) because the bare letters V-A-P-I don't cue the short /æ/. For macOS say, respell as "vappy" for a reliable short-a.

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.
