VULK vs Bolt
Both build apps from prompts. VULK ships across 8 platforms — Bolt focuses on web.
Bolt.new by StackBlitz pioneered browser-based AI app generation with WebContainers. It runs a real Node.js environment in your browser tab, which means zero setup and fast iteration for React web apps. VULK takes a different approach — server-side rendering, 8 platform targets, and 16 AI models you choose from. Both tools generate full-stack code from natural language, but they made very different architectural bets.
