If we get the Bun-ification of every package manager and language ecosystem that would be an awesome thing. This is a great trend.

I'm not a Python dev, but I appreciate the motivation uv has inspired across other package managers. I tried another brew replacement called zerobrew last month. It installed packages to a different directory from homebrew, so I didn't actually test drive after seeing that. Regardless, I look forward to the competition pushing mainstream tools to improve their performance.

And why does speed matter in this case?

Does it reinstall postgres for every package install?

I've been looking for something like this, especially to use only with casks now that Homebrew has removed support for not adding the quarantine bit. Looking forward to giving it a try!

what happens if I test this tool by installing some packages and then remove (the tool)? will I still be able to use Homebrew to manage these new packages?

The current version of brew has a flaw where the installer can't install isolated dependency trees in a sterile manner. If you have packages A, B, C, and D that all have updates, and assuming A,B,C depend on each other and come out to a total of say 1MB, and D is 1000MB, brew works in a MapReduce manner where it will attempt to finish downloading everything in parallel (even though the real bottleneck is D) before doing any installation.

Since the first 3 has no dependency on D, a better way would be to install them in parallel while D is still downloading.
