Deno
A JavaScript and TypeScript runtime developed by Node.js creator Ryan Dahl, featuring native TypeScript support and a focus on security.
Timeline (last 90 days)
An OpenAI red-team test found an unauthenticated remote code execution vulnerability in the Brotli compression library, affecting software such as Node.js, Bun and Deno, and it has been reported and fixed.
The backends listed in the Deep Agents sandbox documentation include Modal, Daytona, Deno and Node VFS.
The Deno sandbox leans toward lightweight JavaScript/TypeScript runtime isolation, with a finer-grained permission model but a limited ecosystem.
The team mapped cloudflare:workers to a 10-line stub class in deno.json, enabling deno test to run native tests directly against Durable Object classes.
Deno's official statement: the runtime will continue to be maintained for one year (including monthly bug fixes and security updates), after which development will stop but it will remain open source; the paid Deno Deploy service will shut down after six months of operation, with support for paid users to migrate to Cloudflare Workers.
The video's author has never used Deno and has always been a Bun user.
On October 9, 2026, Ryan Dahl announced that the Deno team was joining Cloudflare.
Deno's response is to not execute arbitrary code by default, require explicit permission declarations (--allow-net, --allow-read, etc.), and pin dependencies to URLs or integrity hashes.
Over the past year, about 50% of Deno's commits and nearly half of its lines of code have been devoted to Node compatibility.
In August 2026, Ryan Dahl released the open source project Cell D, and two months later the entire Deno team joined Cloudflare, with Cell D at the core of that acquisition.

50%UnverifiedRyan Dahl said that Deno ultimately did not solve the big problem, was sucked into the gravity well of Node compatibility, and was forced to behave exactly like Node.
