Deno’s team is joining Cloudflare, and the Deno runtime will wind down over the next year. Cloudflare will continue operating the JSR JavaScript registry on its infrastructure, while the team works to merge Deno’s celld technology into workerd, Cloudflare’s open-source runtime for Workers. Ryan Dahl announced the move two years after Deno 2 shipped; Bun joined Anthropic about 10 months earlier. Deno launched in 2020 with deny-by-default permissions, first-class TypeScript, web-standard server APIs, ES modules, a single executable and URL-based dependencies instead of npm packages and node_modules. It later added deps.ts, lock files, import maps and npm compatibility; Deno 2, released in October 2024, added full Node and npm compatibility. The source credits competing runtimes with accelerating Node additions including global fetch, WebSocket, Web Streams, Web Crypto, a stable permission model, type stripping, node:sqlite and require(esm). It also cites competition among package managers as contributing to deterministic lockfiles, workspaces, offline caches, smaller node_modules installations and changes to install-script defaults. GitHub announced in June that npm 12 would stop running install scripts by default after supply-chain worms. The source says a community Deno fork could test demand for an independent secure-by-default, standards-focused runtime.
