Deno joins Cloudflare: Deno Deploy shuts down in six months

9 October 2026: Deno's whole team is joining Cloudflare, and the consequences for customers come with firm dates. Deno Deploy, the hosted platform, runs for six more months and then closes. The Deno runtime keeps getting monthly bug and security releases for one year, after which Deno says it will end its own development of it.

Not yet independently verified. Neither post states deal terms or price. Subhosting is not addressed in the Deno post. We will update this when it can be confirmed, and remove this note.

Deno founder Ryan Dahl wrote that the team will merge its work with Cloudflare's Workers and Durable Objects teams and build on one shared platform rather than a separate runtime and host. Paying Deno Deploy customers get migration support to Cloudflare Workers. The Deno post says: "We know this is a consequential change for people who have built on Deno."

What continues

The runtime stays open source, and Deno invites outside maintainers who want to take it over, so a community fork is possible but nobody has been named. JSR, the JavaScript package registry Deno runs, keeps operating with its infrastructure moving to Cloudflare. Work on rusty_v8, the Rust bindings to Google's V8 engine, continues, with plans to integrate it into workerd, Cloudflare's open-source Workers runtime. Deno Subhosting, which appears in the product list, is not addressed in the announcement.

Cloudflare's side

Cloudflare's own post says the Deno team is joining and that Ryan Dahl and Bert Belder will lead an effort to make self-hosting workerd a first-class way to run Workers-style applications. Code and ideas from Dahl's celld project will be merged back into workerd. Cloudflare says more announcements will follow in the coming months. Neither company discloses price or deal structure.

Dahl's celld builds on the Workers programming model and centres on Durable Objects, which he sees as suited to AI agent workloads. Teams running production apps on Deno Deploy have until roughly April 2027 to move, going by the six-month window from the 9 October announcement.
