Bubble is a full-stack no-code platform built on a proprietary visual programming engine that compiles user-defined workflows, data schemas, and UI components into production-ready web applications. The platform provides a built-in relational-style database, server-side workflows (API workflows), front-end responsive design tools, and a plugin API for extending functionality. Bubble exposes a Data API and Workflow API that allow external systems to read/write data and trigger server-side actions via REST endpoints. The AI app builder layer uses large language models (leveraging OpenAI) to interpret natural language prompts and scaffold app structures, pages, data types, and workflows programmatically.
