Socket reported on 16 October that Cloudflare is acquiring the team behind Deno, a runtime for JavaScript and TypeScript. Socket said creator Ryan Dahl announced the deal on 9 October. Deno gets monthly bug and security fixes for a year, then development ends. Deno Deploy, its hosting service, shuts in six months, with move help for paying customers. A 15 October update, per Socket, promises Deno 2.9.x releases through October 2027, with no new features.
Socket said the deal grew from celld, a Deno project. Cloudflare's open source runtime, workerd, ran Durable Objects on a single instance only. These are small units that keep code and saved data together, each backed by SQLite. Cloudflare's own scaled version needed infrastructure that self-hosters lack. Celld spreads those objects across machines. Dahl and Bert Belder will merge it into workerd, so the team turns away from a standalone runtime. Socket gave no price. The team is still weighing how to run development after October 2027. Two community forks have started, Ende and Dodo. Dodo has no releases yet and must be built from source.
Deno's upkeep rested on one company, and that company's attention moved to another problem. Ask which runtimes your products depend on, who pays for them, and what your exit plan is. Check whether anything runs on Deno Deploy, and whether any fork has releases.
