Bolt.new wins for fast, throwaway prototypes and designers; Replit Agent wins for real apps you want to deploy, host, and keep running. Replit has a clearer path from idea to production in 2027.
Replit Agent (launched 2024, matured 2027) builds full apps in your browser — from prompt to database, auth, hosting, and custom domain — all within Replit's integrated cloud. Used by 30M+ developers and non-developers in 2027. Deploy in one click.
Bolt.new (by StackBlitz) runs an entire Node.js environment in your browser via WebContainers. Generates React/Vite apps from prompts with stunning UI quality. Great for prototypes, landing pages, and demos, but hosting and data persistence require external services.

Bolt.new produces the most beautiful prototypes; Replit Agent produces the most production-ready apps. If you only build once, pick Bolt. If you build to ship and maintain, pick Replit.
Prototype or demo in 20 minutes → Bolt.new. Ship a real app you'll maintain → Replit Agent. Many founders use both — Bolt for exploration, Replit for production.
