What it is

A modern runtime for JavaScript and TypeScript.

GitHub

Where it is used

  • Netlify — Netlify used Deno Subhosting to build and ship its edge functions product within weeks, choosing it over building their own solution on AWS Lambda. Source

What people are saying

I love Deno and I use this, but I really wish they would fix this dumb bug: https://github.com/denoland/deno/issues/16466

> Seems like the core of these issues was a Claude-coauthored PR: https://github.com/denoland/deno/pull/33208 Disclaimer: I'm the author of the linked PR. Using AI here is not really at fault here - it was just a giant rewrite that replaced how we do `node:http` in Deno. Replacing the engine while driving is never easy and we did the best we could. While we have a lot of test coverage and we use tests directly from Node.js codebase, we just don't catch everything. We're constantly working on improving the situation and I'm sorry you hit a problem. I can assure you that we are fixing all Node compat bugs as quickly as possible.
In Deno 2.9
To be honest, Deno was cool in the past (I even somewhat promoted it on HN in some comments), but nowadays I'm disappointed in their lackluster approach to stability and testing (specifically in Node compat). I recently hit multiple Node compatibility regressions in Deno that were hard to debug, and it doesn't help that they use Claude for everything now, from actual fixes to writing blog posts (even this one). For example, those two issues recently directly affected my projects: - https://github.com/denoland/deno/issues/34297 - https://github.com/denoland/deno/issues/35289 Seems like the core of these issues was a Claude-coauthored PR: https://github.com/denoland/deno/pull/33208 I think I'll probably just go back to normal Node because it's stable and won't break things like this between minor releases, plus it's not full-on vibe-develop

ed like Deno and Bun. P.S.: Deno does genuinely have good parts: built-in type checking, LSP server, formatter with sane defaults, and so on. I'm just very disappointed that they seem to be focusing less on the actual core runtime.
In Deno 2.9
from what i understand after a quick look at the source is it uses a C ABI to communicate between the WebView/CEF "host" application and the deno runtime which is loaded by the host as a shared library. marshalling of values back and forth between the JS/C++/Rust layers still has to happen but these are just straight C api calls in process under the hood so much less overhead than having to do serdes across a socket/pipe. - https://github.com/denoland/deno/blob/main/cli/rt_desktop/li... - https://github.com/littledivy/laufey/blob/main/webview/src/m...
In Deno Desktop
I remember looking into the nodejs alternatives some years ago, one way to compare them is to look at the open issues. bun had so many hits for 'segfault' and deno has basically none. Even now: bun (zig) [1] 119 open / 885 closed deno (rust) [2] 0 open / 1 closed I don't think this has that much to do with Zig's anti-AI stance. More about using the right tool for the job.

In Bun's experimental Rust rewrite hits 99.8% test compatibility on Linux x64 glibc
The article is measuring full project build performance. That includes type-checking and compilation. Maybe the `tsc` type-checker was already fast (so we only get some speed improvements in `tsgo`), or the `tsc` compiler was not that fast (so we get a lot of speed improvements in `tsgo`)? *Update:* There was a performance regression in incremental type-checking between `tsgo` preview 20251209 and 20251211 [1]. But `deno` is using `tsgo` 0.1.11 which was already released last week (before this regression). So, does not seem to influence the type-checking times here.
