- great lock update behavior by default (though --no-update became the default in poetry 2.0)

- speed, as others have said (5 minutes → 70 seconds for our docker build)

- much easier (and faster) virtual environment management than poetry, should you want a venv

- manages the python version, including new GIL-less variants if you want to try them

- script dependencies (include requirements as a comment in a script and it will install and use them)

I've been using uv as a drop-in replacement for poetry. My little usage of it so far has led me to view it as just a better poetry. Does the same things I wanted from poetry, but faster and I haven't hit the dependency resolve issues I hit with poetry in the past (tbf, I think these got fixed in poetry since).

Uv will manage python versions for you.

Speed! You won't go back

It’s way way faster for one.
