Cloudflare acquires Astro team, keeps it open source with multiple deployment targets

Cloudflare announced on Friday that it will acquire the team behind Astro, the open source JavaScript framework for content driven websites. The Astro team will join Cloudflare as employees, while Astro remains open source and MIT licensed, with its open governance and public development roadmap staying in place, according to the January 16 announcement.

Cloudflare says Astro will continue to support a wide set of deployment targets, not only Cloudflare. In its statements, Cloudflare frames the acquisition as a long term investment in an open source project it already uses, and says the deal lets the team double down on Astro’s focus on content driven websites.

Cloudflare also points to performance as a core reason for the move, noting that heavy client side JavaScript can slow initial rendering and affect search ranking and conversions. Astro’s approach emphasizes shipping only the code needed per page, using its Islands architecture to keep most pages static HTML with smaller interactive components, and it remains UI agnostic so developers can use components from frameworks like React, Svelte, and Vue.
