Cloudflare is acquiring the team behind Deno, the JavaScript and TypeScript runtime, and will wind down Deno's own hosting service and runtime development over the next year, Deno said in a blog post Oct. 9.
Deno's runtime will get monthly bug fixes and security updates for one year before development ends, though the project will remain open source for the community to continue, according to the post. Deno Deploy, the company's hosting service, will shut down in six months, with Cloudflare offering migration help to paying customers who move to Cloudflare Workers. The JSR package registry will keep running under Cloudflare's infrastructure.
Deno co-founder Ryan Dahl said the move follows the logic of the company's own roadmap, pointing to Celld, an open-source project Deno launched in August that recreated Cloudflare's Workers and Durable Objects model for self-hosted use. "The progression from Deno to Deno Deploy to Celld explains why this move makes sense to us," Dahl said. Cloudflare plans to merge Celld into its existing Workerd runtime, with Dahl and co-founder Bert Belder leading the effort, according to the blog post.
Teams that built on Deno Deploy now have six months to migrate, and anyone treating Deno as a long-term Node.js alternative just watched its creator fold the project into a bigger platform instead of growing it independently.
