Poly vs. the alternatives
An honest side-by-side. Poly's pitch isn't "better than everything" -- it's "one command, whichever of these already has the package."

Poly isn't trying to replace pip, npm, or Homebrew -- it shells out to them. Think of it as the one command you remember, not a competing package manager for any single ecosystem.
