How we compiled this
Pricing fetched directly from each vendor's official /pricing page on 2026-06-14. Retool's pricing page geo-redirected to EUR; USD figures sourced from GetApp (getapp.com) and SoftwareAdvice, which both independently show Team=$10/seat/mo and Business=$50/seat/mo — consistent with EUR figures at current exchange rates. All prices reflect the smallest billable unit (one seat). Annual rates are the annualized monthly equivalent. monthlyUsd on per_seat plans = price for one seat. Quote-only / contact-sales tiers recorded as null. Non-telephony vertical: minutesIncluded, callsIncluded, overagePerMin, overagePerCall are null on every plan.
