Reviewer scorecard
“AI-generated full-stack apps running instantly in the browser. The StackBlitz WebContainer foundation makes it actually work.”
“Typed errors and dependency injection for TypeScript done right. The platform modules (HTTP, Schema, SQL) are production-grade.”
“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.”
“Effect brings Scala/Haskell-level reliability to TypeScript. As TypeScript applications grow in complexity, Effect becomes more valuable.”
“Steep learning curve and the functional programming style isn't for everyone. The benefits are real but the adoption cost is high.”
