Deno team joins Cloudflare: Deno runtime gets one more year of fixes, Deno Deploy shuts down in six months, celld folds into workerd for self-hosted agent infra
On Oct 9 Ryan Dahl announced the whole Deno team is joining Cloudflare. Deno runtime gets one more year of monthly bugfix/security releases, then official development ends (it stays open source); Deno Deploy runs six more months before shutting down, with migration help to Workers; JSR continues. Focus shifts to the Workers/Durable Objects model and merging self-hosted celld into workerd, pitched explicitly at agent harnesses.
Key Takeaways
- Timeline: Deno runtime gets 12 months of monthly fixes then official development ends; Deno Deploy shuts down in 6 months with migration support for paying customers
- JSR keeps running on Cloudflare infra; rusty_v8 stays supported and heads into workerd
- celld (Apache-2.0, ~5.3k stars, v0.6.2 beta): a 58 MB static binary for self-hosted distributed Durable Objects backed by one S3-compatible bucket
- Vendor-reported celld numbers: 0.47 MB RAM per resident cell, 2,500 cells per 8 GB node, 0.2/0.3 ms p50/p99 stateless requests, ~20 s failover with zero lost acknowledged writes
