Cloudflare acquires Deno and will end Deno Deploy in six months
Cloudflare will run Deno Deploy for six months, support the Deno runtime for one year, and keep JSR alive; Deno Deploy users should plan a Workers migration now.

Cloudflare acquired Deno and is bringing the whole team into its Workers effort. Deno says future work will move into celld, a shared platform intended to combine the runtime, Workers and Durable Objects for distributed applications with persistent state, WebSockets and serverless execution. Cloudflare and TechCrunch report that financial terms were not disclosed; Deno had raised about $26 million. JSR, Deno's JavaScript registry, is expected to continue.
The migration dates are the part builders need: Deno Deploy is planned to operate for six months before shutting down, while Deno runtime support is planned for another year before development ends. The alternative is not a neutral wait; it is a choice between moving to Workers, hosting Deno yourself or rewriting the service. Inventory Deploy use, storage, scheduled jobs and edge permissions before the deadline turns into an outage.
What you can do with it
Read the Deno and Cloudflare notices, list every Deno Deploy service and map its state, scheduled work and outbound calls. Create one Workers migration branch with a small route and persistent-state test. Keep the original deployment available until the new path passes traffic and rollback checks.
Our take
Cloudflare gets a mature runtime team and Deno users get a plausible migration path, but users still absorb the work. Six months is short for a production move involving state and WebSockets. The deal is good news only for teams that start the inventory now; waiting for perfect compatibility is the risky choice.
