Verdict

We are not publishing a free-tier verdict for either Kong or X (Twitter). The page we cite for Kong states no amount, tier or rate we can read when we last looked, on 2026-10-08. We could not read the page we cite for X (Twitter) when we last looked, on 2026-11-09. We are not comparing the two pricing histories.

A verdict here is not a fixed property of the vendor. A one-off pricing event demotes a vendor while its recorded date falls in the last 180 days and then lapses on its own, with nothing about the vendor having changed; a standing condition — a free tier withdrawn and not restored, a product retired — does not lapse with time. A badge carrying a date states the record it rests on; a badge with no date rests on no record in force.
