As of February 2026, over 3 million apps have been built on Bubble, including successful startups that have raised venture funding and scaled to thousands of users. The platform provides complete control over design with pixel-perfect customization, responsive layouts that work on any device, and a built-in database with privacy rules and permissions. Bubble's workflow system handles complex logic including conditional actions, API calls, data manipulation, and scheduled tasks. The platform supports custom domains, SEO optimization, and integrates with 1000+ services through native plugins and APIs. For developers, Bubble offers custom plugin development, JavaScript integration, and version control. The platform scales automatically with your application, and higher-tier plans include dedicated instances for better performance. Bubble's active community provides templates, plugins, and learning resources, making it possible for non-technical founders to build and launch sophisticated SaaS products, marketplaces, social networks, and business tools.
