🟠Vercel Acquires NuxtLabs Vercel has acquired the company that caretakes the Nuxt project and employs some of its core team – a move Vue creator Evan You is quite optimistic about. Vercel now manages, or at least supports, several key projects like Next.js, Turborepo, Svelte, and shadcn/ui. Nuxt itself remains open source and has a promising future. Vercel’s Guillermo Rauch shares a little more about the move here. NuxtLabs / Vercel
