What is Deno?
Deno is a secure JavaScript and TypeScript runtime built on V8 and Rust, created by Ryan Dahl (the original creator of Node.js). It runs TypeScript natively without a compilation step, has secure-by-default sandboxing, and implements modern web standard APIs. Deno 2 brings full Node.js and npm compatibility.

apt update🆓 There is an always-free mirror. deb-free.griffo.io serves packages free forever — no account, no subscription, at most 2 months behind upstream, security fixes immediately. It currently carries Ghostty, Oh My Posh and Zed; Deno is not one of them, so the repository above is the only way to get it today — ask and it can be enrolled.
📋 Available Deno Packages
deb.griffo.io provides two different Deno packages to suit different needs:
Full Deno runtime with all developer tooling including the REPL, LSP, formatter, linter, test runner, and bundler. This is the recommended choice for most developers.
sudo apt install denoapt install denoLightweight Deno runtime without the developer tooling. Ideal for production deployments where you only need to run compiled Deno programs with minimal overhead and a smaller binary footprint.
