The most focused and precise tool here. Describe a screen to get working React code ready to copy into your project. You can start from sketch or screenshot uploads. It does not handle backends or storage, and the small free credit limit runs out quickly after a few edits.
Best for turning a single prompt into a working app quickly. Perfect for building a 1-day demo by chatting to refine screens. Since free limits are token-based, repeated edits burn limits fast. As apps grow, unrelated parts may break, so save working versions often.
The lowest barrier for non-coders. It generates polished initial UIs and handles auth and database setups automatically. You can export clean code to GitHub. Free daily messages are limited, complex apps can break during edits, and connected 3rd-party services may charge extra.
The only tool here focused on direct coding. Opens an instant cloud environment in your browser, making it great for learning and testing. Deployment is simple. Free AI features are trial-only with usage-based costs, and public projects expose code, so keep API keys secret.
Choose based on how much you need built. Pick v0 for UI components, Bolt for a working full-stack prototype, Lovable for a complete app with auth and storage, or Replit to learn real coding. Note that token limits deplete faster than message limits. Since there are no Korean alternatives yet, all four are global tools. Always save working code backups and keep API keys in secret configs.
