Build web apps visually without writing code

4.5/5 across G2 and Capterra · 499 ratings, Sep 2026

Bubble enables building full web applications without code. Not just websites-applications with user accounts, databases, workflows, and business logic. It's positioned for entrepreneurs and teams who need to build and iterate on products without engineering resources. The visual programming model is comprehensive. Design interfaces with a drag-and-drop editor. Define data types and relationships. Build workflows that respond to user actions. The capability approaches what you could build with code, though the paradigm differs. The database is built in. Define types (users, orders, posts), set fields, and create relationships. No external database to configure. Data is accessed through visual queries, and permissions control who sees what. Workflows handle application logic. When a button is clicked, create a record, send an email, and navigate to a page. Workflows can be simple or complex, with conditions, loops, and API calls. This is where the logic of your application lives. Plugins extend functionality. Payment processing, maps, charts, authentication-plugins add capabilities without building from scratch. The marketplace has hundreds of options for common needs. Responsive design requires attention. Bubble can create mobile-friendly layouts, but it takes effort. The default desktop-first design needs deliberate responsive configuration. The applications run on Bubble's infrastructure. This simplifies deployment but creates vendor dependency. For many use cases, this trade-off is acceptable for the development speed gained. Bubble isn't for every application. Performance-intensive, highly custom, or scale-critical applications may outgrow it. But for validating ideas, internal tools, and many production applications, Bubble delivers remarkable capability.
