JDoodle.ai is a 2026 chat-based no-code AI builder that turns natural language ideas into live websites, apps, prototypes, mockups, or micro-tools—without writing code. Describe your vision, watch the AI agent generate React/JS code, auto-test/fix bugs for free, add database & hosting, then publish. PAYG credits only when you build/iterate; free to start. Great for founders validating ideas, marketers creating landing pages, PMs prototyping features, or non-tech users launching fast MVPs.
