“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“Describe an app, see it running immediately. The fastest path from idea to working prototype.”
“bolt.new represents the convergence of AI generation and instant execution. This is how rapid prototyping will work.”
