Bubble

Bubble is the most powerful no-code development platform, enabling anyone to build fully functional web applications with complex logic, databases, user authentication, and API integrations — all without writing a single line of code. Used by over 3 million builders, Bubble has been used to create SaaS products, marketplaces, CRMs, social networks, and internal tools that serve millions of users.

Key features include a visual drag-and-drop editor for pixel-perfect UI design, a powerful visual programming system for backend logic (workflows), built-in database with relational capabilities, user authentication and role-based permissions, REST API connector for integrating any external service, plugin marketplace with thousands of extensions, responsive design engine, version control, and the ability to host and scale applications on Bubble’s infrastructure. Recent AI additions include AI-assisted app building and natural language workflow creation.

Bubble offers a generous free plan for building and testing. The Starter plan costs $32/month for custom domain and basic features, the Growth plan at $134/month adds more capacity and server logs, the Team plan at $358/month includes collaboration and branching, and the Enterprise plan offers dedicated infrastructure. Bubble is the gold standard for no-code development — while other tools offer simpler builders, Bubble is the only no-code platform capable of building production-grade, scalable applications.
