How to pronounce SPIFFE

SPIFFE is most commonly pronounced "spiffy" (/ˈspɪfi/). This is the widely-used reading among engineers, though edge cases exist.

SPIFFE (Secure Production Identity Framework For Everyone) is a CNCF graduated standard that gives every workload a cryptographic identity (an SVID) so services can do zero-trust mTLS without baked-in secrets; its implementation is SPIRE. It is spoken as a word, not letter-by-letter, and the trailing -E is voiced: it is pronounced exactly like the English word "spiffy", rhyming with jiffy. The two traps are saying "spiff" with a silent E, or spelling it out S-P-I-F-F-E.

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.
