Cloudflare Acquires Deno: What Changed?

FAQ

What is Deno and why was it important?

Deno is an open source JavaScript and TypeScript runtime created by Ryan Dahl, the creator of Node.js, as a more secure and simpler alternative. It stood out for its granular permissions system that specifies which files, folders, and network hosts a script can access.

How does Cloudflare's acquisition of Deno affect developers in the Middle East?

Developers running Deno in production have one year to plan a migration. Those using Cloudflare Workers should benefit from workerd improvements and self-hosting via celld, which could lower infrastructure costs and increase flexibility.

What is celld and how does it differ from Deno?

celld is an open source implementation of the Durable Objects pattern from Cloudflare Workers, released by the Deno team in August. It relies only on object storage for coordination and persistence, offering a new server development model rather than just a different API.

Should MENA teams switch away from Deno now?

If teams run Deno in production, it is wise to start evaluating alternatives over the coming year. New teams may find Cloudflare Workers or Node.js more sustainable long-term options.
