Deno Team Moves to Cloudflare: Runtime to Receive One Year of Support
The entire Deno team is moving to Cloudflare. The Deno runtime will receive fixes for another year, while Deno Deploy is expected to remain operational for six months.
Deno team moves to Cloudflare were announced by Deno on October 9, 2026. The entire project team is moving to Cloudflare. The change affects development of the Deno runtime, the Deno Deploy hosting service, and the JavaScript Registry (JSR).
The original team will support the Deno runtime for another year with monthly bug fixes and security updates. After that period, its further development by Deno is expected to end. The project is expected to remain open source.
Deno team moves to Cloudflare and service timeline
The shortest timeline applies to Deno Deploy. The platform is expected to remain operational for another six months. According to the announcement, paying customers are expected to receive support migrating to Cloudflare Workers.
Deno has not yet published exact end dates for Deno Deploy or details about migration tools or product replacements for all users. Organizations using the service therefore have a limited period to plan the move and must follow further information from the operators.
JSR is expected to continue operating. Its infrastructure will move to Cloudflare. The announcement does not provide further technical changes to how the registry works.
One year of Deno runtime support includes security fixes
For users of the runtime itself, the key point is that monthly updates, including security fixes, are confirmed for only one year. The original Deno team will then end further runtime development. Since Deno is expected to remain open source, it has not yet been confirmed whether, or by whom, its long-term maintenance will be taken over after this period ends.
From a security perspective, this means teams deploying Deno should monitor the support schedule and prepare for the period after support ends. The announcement does not specify the conditions for security updates after the one-year period expires.
Cloudflare wants to combine celld and workerd
Cloudflare said it wants to combine the celld and workerd projects. The goal is for supported self-hosting of Workers and Durable Objects to be a first-class scenario.
Cloudflare is thus acquiring the team around Deno as well as the celld technology. According to the available announcements, however, the financial terms, transaction structure, and exact legal scope of the transfer of Deno Land’s assets are not known.
Further information is expected especially on the date Deno Deploy will end, the migration process to Workers, future support for the Deno runtime, and the plan to connect celld with workerd.
