Common questions about OpenFaaS, answered from independent, dated evidence.

OpenFaaS supports Linux and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for OpenFaaS, not the verdict.
