Why these ones

An alternative here means a product in the same category as FormatJS (Localization I18N), ranked by the vioscaleAI composite: a confidence-weighted blend of independent signals such as adoption, release activity, pricing transparency and security posture. There are no user reviews in it, and no vendor can pay to appear or to rank higher. Where we have not confirmed something, we show that rather than guessing.
