Astro Technology Company, maker of the Astro web framework, has just been acquired by Cloudflare. The company also just released Astro 6 in beta, with the update featuring a redesigned development server.

The merger with Cloudflare means Astro remains open source and MIT-licensed and continues to be actively maintained, according to the January 16 announcement. In addition, Astro will continue to support a wide set of deployment targets, not only Cloudflare, and Astro’s open governance and development roadmap remain in place. Full-time employees of The Astro Technology Company are now employees of Cloudflare, said the announcement.

A separate blog post on January 13 provided instructions for accessing the Astro 6 beta. The Astro 6 development server refactor brings Astro’s development and production code paths much closer and increases Astro’s stability on all runtimes, according to the announcement. The release also unlocks first-class support for Astro on the Cloudflare Workers platform for building applications across the Cloudflare global network.

Astro 6 also features the Content Security Policy (CSP) feature, which helps protect sites against cross-site scripting (XSS) and other code injection attacks by controlling which resources can be loaded. Previously released as an experimental feature in Astro 5.9, CSP is stable in Astro 6. Also stabilized is Astro 5.10’s experimental Live Content Collections (LCC) feature. LCC builds on Astro’s Type-safe Content Collections feature, which lets users fetch content either locally or from a CMS, API, database, or other sources, with a unified API working across all content.
