Deno is joining Cloudflare
Cloudflare is acquiring Deno outright. The plan is to build on celld — the Deno team's open-source (August 2026) implementation of Cloudflare's Durable Objects pattern — to make workerd self-hosting a first-class way to run apps with the Workers programming model. However, the Deno runtime itself will only be maintained for one more year (monthly bug/security releases), after which development ends, though it stays open source. Ryan Dahl said the decision was joint: Deno is well engineered but "not solving big problems," having been pulled into Node compatibility. He sees celld, which coordinates and persists via object storage only, as an entirely new server development model. Author notes Deno's per-file/host permission system; Node gained a similar permissions model in v20 (April 2023), stable in v22.13.0, but without network host allow-listing.
