Bun is basically Node.js — compatible with it, built around it, and its main selling point is speed. But I don’t like Node.js. Node without something like Vite in between has always been a pain, and Bun doubling down on that design doesn’t make it more appealing. If I’m trying to get away from Node, why would I pick a faster version of it?

Deno is different. Here’s what I actually like about it:

It feels like the browser. Imports work the way they do in browser JS/TS. No magic resolution, no CommonJS quirks. It just makes sense.

The Deno namespace is clean and modern. The standard APIs are well-designed and don’t carry decades of legacy baggage.

JSR and @std packages. Finally a registry that feels right for TypeScript-first development.

Single-file scripts with shebangs. I can write a .ts file, throw a shebang on it, and run it — with dependencies — immediately. No install step. Deno is also a great REPL; just open the terminal, type deno, and start importing and computing.

deno compile. Ship a single binary. Straightforward.

Permissions as a feature. This is underrated. Deno’s permission model isn’t just a security sandbox — it’s a clean foundation for plugin systems. If you support JS/TS plugins through Deno, you automatically get WASM support too, since it’s all just JS. And you get isolation with permission prompts out of the box. Same idea applies to LLM agents: let the agent execute only through Deno with restricted permissions, and you have something actually isolated and auditable.

Built-in lint and fmt. One less thing to set up.

deno.json instead of tsconfig.json + everything else. Less configuration surface, less noise.

Trust. I hit segfaults with Bun a few times. That erodes confidence fast. Deno is written in Rust, and it shows in the stability.

Deno isn’t just faster Node. It’s a better-designed runtime that happens to also be fast. I don’t want more bloat at higher speed — I want something clean that gets out of my way. That’s Deno.

Speed is not the point. Deno will keep getting even faster. The point is that it’s a well-designed runtime that gets out of your way — clean, modern, smooth. I don’t want faster Node with more bloat. I want Deno. And its already faster than Node.
