Webflow wanted $2,500 for one language. AI rebuilt our whole site in a weekend

Rezi.ai describes moving its ~515-page site off Webflow to an Astro 7, React 19 and Tailwind CSS 4 stack hosted on Netlify, with Claude Opus 5.5 doing the heavy lifting, after Webflow quoted $2,500 a year to add a single language on top of a roughly $30,000-per-year enterprise contract. The team first tested the approach on two smaller brands, then kept the Rezi.ai rebuild visually identical using a script that compares every page to the Webflow original, and reports desktop PageSpeed rising from 38 to 99 and mobile from 57 to 95.
