Bubble is a no-code platform for building web apps and native iOS and Android apps in one visual editor, with a managed database, visual workflows, plugins and an API connector. An AI builder can generate an initial app from a plain-language description. Apps are hosted on Bubble's infrastructure and metered in workload units.
Bubble lets people design pages by drag-and-drop, define data types in a managed database and express logic as workflows that respond to user actions, without writing code. Web apps and native mobile apps are built in the same editor and share one database, user authentication and workflows; mobile apps can be submitted to the Apple App Store and Google Play. An AI agent can draft an app blueprint from a description, which is then refined in the editor.
Third-party services are reached through community plugins, Bubble's API connector, an app connector and a SQL connector. Bubble hosts the engine and database on AWS with assets served through a CDN, and manages backups and restoration. Server usage is measured in workload units (WU); each plan includes a monthly WU allotment, and additional usage can be covered by workload tiers or pay-as-you-go overages.
Plans are purchased per project rather than per user. The Free plan is intended for apps under construction (one editor, 50K WU per month, development version only); paid plans are shown with annual billing and add live deployment, custom domains, more editors, longer server logs, version control and build submissions. Enterprise adds hosting-location choice and custom limits.
