Speed, simplicity, and fewer moving parts. Bun replaced Node + tsx + Jest + dotenv in one binary — our backend runs TypeScript natively with zero config. The built-in test runner, auto-loaded .env files, and native SQLite support removed a lot of tooling overhead. Cold starts are noticeably faster, which matters for our RAG pipeline where every millisecond counts. We switched from Node early on and never looked back.
Bun is around for quite some time, I wonder why it never made it to PH. Also, haven't they been bought by Anthropic now?
Product Hunt
@phil_co I was surprised it didn't launch before and correct!

I ❤️ bun. But I made sure my project also works with NPM. Turned out. Bun didn't support windows arm executables. But NPM did. So for win arm exe. I use NPM. For other targets. Bun.

Recently deployed a microservice for our app with Bun and it was such a refreshing DX!
I'm a long-time user - mostly for personal projects, and I’ve even been able to use Bun as a drop-in replacement for some of my Node projects - but this is our first time taking it to production, and so far it’s been great.
Amazing work by the team at Bun, I still remember the 1.0 video - they've come LONG way. 🚀

Bun has been acquired by Anthropic! Wow, big news!
Incredible
You guys would do a better jobs in the future with recent colloborations
Do you plan to enhance compatibility with Node.js-specific APIs (to lower migration friction for existing Node.js projects)? Also, will Bun add support for additional package management tools (e.g., Yarn) alongside its built-in npm client?
