Reviewer scorecard
“AI-generated full-stack apps running instantly in the browser. The StackBlitz WebContainer foundation makes it actually work.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“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.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
