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180 days and then lapses on its own, with nothing about the vendor having changed; a standing condition — a free tier withdrawn and not restored, a product retired — does not lapse with time. This one rests on a record effective 2026-08-24, so it lapses on 2027-02-21 unless we record something new first.

Retracted — this record was our error (2026-11-08). Retracted 2026-11-08: this record misread GrowthBook's page. The Open Source plan did not take Cloud Starter's 3-user limit: GrowthBook's FAQ says the free self-hosted plan has unlimited users. What changed is that both free plans were limited to 1 project, recorded separately with its archive dates. Unconfirmed. We could not check this change against an archived copy of GrowthBook's page, so it does not count toward the rating.Source ↗
