The Launch of CodePen 2.0

CodePen 2.0 has officially launched, combining the Classic Pen and Project editors into a single, extensible editor. Key new features include one-click deployment to a *.codepen.app subdomain with custom domain support, a built-in file system, version history, real-time collaborative editing, and a Blocks system for mixing technologies via the CodePen Compiler. The editor now supports Vite-powered Vue, Tailwind, Lightning CSS, MJML, and Nunjucks. The Classic Editor remains accessible but is no longer prominently linked. AI features are being explored but not yet available. Users familiar with the Classic Editor can replicate that experience using the Classic Block and Minimal UI mode.
