I used poetry professionally for a couple of years and hit so many bugs, it was definitely not a smooth experience. Granted that was probably 3-4 years ago.

I always loved poetry but then I’d always run into that bug where you can’t use repos with authentication. So I’d always go somewhere else eventually.

Some time ago I found out it does work with authentication, but their “counter ascii animation” just covers it… bug has been open for years now…

The very first time I tried to use Poetry I ran into a bug where it couldn't resolve some simple dependencies.

uv actually works.

I started using poetry abiut 4 years ago and definitely hit a lot of bugs around that time, but it seems to have improved considerably. That said, my company has largely moved to uv as it does seem easier to use (particularly for devs coming from other languages).

I've occasionally run into performance issues and bugs with dependency resolution / updates. Not so much recently, but at a previous company we had a huge monorepo and I've seen it take forever.
