  • From Prompt to Production: Building my Travel Website with Vercel v0
    The AI landscape in 2026 is crowded with powerful options. I chose Vercel and v0 because I recently attended a developer event where I earned some credits and wanted to test its reputation for high speed agentic web deployment. - Source: dev.to / 3 months ago
  • Shadcn Libraries Every Developer Should Know
    You see the same clean layouts, balanced spacing, Tailwind-based styles, and accessible components everywhere. Even AI tools like v0 and Bolt follow Shadcn-style patterns without calling it out. - Source: dev.to / 4 months ago
  • Choosing a Frontend Framework in 2026: When AI Becomes Your "Invisible Teammate"
    In early 2026, when you open v0.app and type a sentence to generate UI, it outputs Next.js + React + shadcn/ui. When you use Lovable to build a product prototype, it's powered by TypeScript + React + Vite + Tailwind. When you're vibe coding on Bolt.new, although it supports multiple frameworks, React is still the default. - Source: dev.to / 5 months ago
  • We Built the v0 iOS App
    It makes more sense if you go to the main landing page: https://v0.app/ Basically like Figma Make or Lovable, a vibe coding app, except now also on mobile, which is cool. - Source: Hacker News / 7 months ago
  • Building Faster with V0 and Claude Code: Lessons Learned from Vibe Coding
    AI tools like Vercel's v0 and Claude Code can help you spin up projects faster than ever. But from my experience in vibe coding, I've learned they're not magic bullets—you still need to know what you're building, understand your data, the problems you are trying to solve, and the tech stack you are using to have good output. (And yes—you still need to know how to code.) Especially with these tools. - Source: dev.to / 9 months ago
