CodePen 2.0 Launch: Real-Time Collaboration and New Features

I recently launched CodePen 2.0, a project requiring more effort than the original creation. This update introduces powerful real-time collaboration, allowing users to invite co-editors and work together seamlessly. We also added support for npm packages, new Blocks like MJML, and direct deployment capabilities. Early tests with live streams and email building proved the platform is robust and ready for complex workflows.
