How do we build these rankings?

Every tool has a review with data verified on its official website (pricing, free plan, API, platforms and languages). The order reflects our editorial rating, which weighs output quality, value for money and real-world usefulness. We review the data regularly, but always confirm the price on the vendor's site before subscribing.
