Webstudio is an open-source, self-hostable visual web builder positioned as a Webflow alternative — offering a professional visual CSS editor with full design control, a component system, and CMS capabilities, all built on open standards without vendor lock-in. Because it's open-source, agencies and developers can self-host Webstudio, modify the builder itself, and avoid the SaaS fees associated with Webflow. Webstudio exports clean, semantic HTML with Tailwind CSS or vanilla CSS — a key differentiator for performance-conscious developers. Sites built with Webstudio load runtime scripts from webstudio.is CDN domains and use webstudio-specific CSS class naming conventions in their published markup. The Webstudio Cloud managed hosting option is free during beta, with commercial plans planned.
