What package managers do you actually use day to day in 2026?

Building dev tooling means picking what to support first. The "popular" answer is not always the real answer — npm is dominant by registry stats, but the developers I talk to are split across yarn, pnpm, bun, and uv depending on team and ecosystem. If you're up for sharing: — Primary package manager you reach for on a new project (npm, yarn, pnpm, bun, pip, uv, poetry, pipx, something else) — Whether that's the same one your team standardizes on, or just your personal preference — Has anything moved in the last 12 months? bun went from "interesting" to "actually shipping" pretty fast, uv similarly on the Python side Building a tool that hooks into all of these (launching tomorrow— Veln) and the assumption I went in with was npm/pnpm dominant on JS, uv eating into pip on Python. Curious whether that matches reality or whether I should be weighting differently.
