Building an app with AI is rapidly evolving, with platforms like Replit, Bolt, and Bubble offering unique features for developers and non-developers. Replit provides an all-in-one programming environment with AI-enhanced coding capabilities and robust collaboration tools, making it more accessible for non-developers compared to Bolt, which focuses on a code-first approach ideal for experienced developers. Bolt offers efficient mobile app development and fast iterations but struggles with consistency and limited free plan usage. In contrast, Bubble stands out as a visual no-code platform, enabling users to build and customize web apps without technical expertise, offering strong design capabilities, built-in security, and seamless integration with tools like Figma and Stripe. While Replit and Bolt cater to those with coding skills, Bubble provides a comprehensive, user-friendly solution for creating scalable, production-grade apps, allowing full control over design and functionality through a drag-and-drop interface.
