Bubble

Bubble is a no-code platform that lets people build full, database-backed web applications through a visual editor, covering the frontend interface, backend data model, and workflow logic all within a single tool, rather than only producing simple static pages or forms the way many lighter no-code website builders do. Users design an application's interface by dragging and arranging elements on a canvas, define a relational data structure similar to a traditional database, and build application logic through a visual workflow editor that supports conditionals, API calls, and complex multi-step processes, which together let Bubble applications support genuinely complex functionality like marketplaces, social networks, and SaaS products rather than being limited to simple internal tools. Its plugin ecosystem extends functionality with pre-built integrations for payments, maps, and other common third-party services, and its API connector lets an application call any external REST API even without an official pre-built plugin. Because applications built in Bubble are fully hosted on Bubble's own infrastructure, founders don't need to manage servers or deployment pipelines separately, though this also means an application's growth and technical ceiling are tied to what Bubble's platform supports. Bubble is widely used by non-technical founders building an MVP to validate a startup idea before investing in custom-coded development, as well as by technical founders who want to move faster on early-stage product iteration than writing full custom code would allow.
