I tried using Bun a few times, and I really liked working with it.

Much better than Node.

However...!

I always managed to hit a road block with Bun and had to go back to Node.

First it was the crypto module that wasn't compatible with Nodejs signatures (now fixed), next Playwright refused working with Bun (via Crawlee).

Playwright support will improve soon. We are rewriting node:http’s client implementation to pass node’s test suite. Expecting that to land next week.
That may be just the best way to drop that you are introducing a rewrite which fixes a set of bugs that affect users
You can use Bun as package manager only. You don't have to use Bun as runtime.
Indeed! also as a test runner/lib if you're not doing browser automation. bun definitely has benefits even if not used as a runtime.
I believe Playwright worked for me with the latest Bun though
Sure?

Does it work if I have packages that have nodejs c++ addons?

Why wouldn’t it? The end result of a npm install or a bun install is that the node_modules folder is structured in the way it needs to be, and I think it can run node-gyp for the packages that need it.
I think this is the big one that slows adoption of "better" / "faster" tooling down, that is, backwards compatibility and drop-in-replacement-ability. Probably a lot of Hyrum's Law.
Deno doesn't work with crawlee either unfortunately
You should try Deno, they have good Node compatibility
Does it? Last I tried, several years ago, coverage of the Node APIs was not good. I wanted to send data over UDP and a lot of Node basics there were missing.
Deno's node compat is way better now.

They're still missing niche things and they tend to target the things that most devs (and their dependencies) are actually using.

But I can see they have it in their compat stuff now and it looks like it's working in the repl locally: https://docs.deno.com/api/node/dgram/

This page tracks Deno's compatibility with Node by running its tests: https://ffmathy.github.io/is-deno-compatible-yet/
Playwright has been fixed one year ago I think.
Storybook is another for me.
