June 2025 Summaries

Cloudflare has announced its support for pkg.pr.new's data infrastructure, which aids developers by creating instantly usable versions of packages for testing and feedback before official releases. This service, maintained by the StackBlitz-labs team, allows users to test packages in a sandboxed environment using WebContainers, and features seamless installation via GitHub integration. With Cloudflare's backing, particularly through Project Alexandria, pkg.pr.new can efficiently scale its operations by utilizing Cloudflare R2 for storage, ensuring fast delivery and efficient handling of large packages. The platform has seen significant adoption, with over a million preview packages released and used by major organizations like Meta, Hugging Face, and Vue.js. The collaboration with Cloudflare ensures sustainable growth and improved service for the open-source community, while also implementing a storage management system that removes unused packages to maintain cost efficiency.
