Bubble

Bubble is the most powerful no-code platform available for building web applications. Unlike website builders that produce static pages, Bubble enables creation of true full-stack web apps — with a custom database, user authentication, business logic, API integrations, and dynamic content — all through a visual editor. The Bubble editor works in three interconnected layers: Design (pixel-perfect UI with responsive layouts), Data (custom database schema with types and fields), and Workflows (event-driven logic that runs when users interact with the app). These layers work together to produce apps indistinguishable from hand-coded products. Bubble's AI features include an AI app generator that produces a starting-point app from a text description, AI-assisted page generation, and native integration with OpenAI and other AI APIs so builders can add chatbots, content generation, and AI features to their apps without backend code. The Bubble Marketplace offers thousands of pre-built templates (SaaS apps, marketplaces, CRMs, social networks) and plugins that extend functionality. A large ecosystem of no-code agencies and developers builds and maintains Bubble apps commercially. Bubble hosts apps on its own infrastructure with automatic scaling. Custom domains, SSL, and geographic redundancy are included. Thousands of startups have launched and scaled real products on Bubble — some raising millions in venture funding.
