A tiny dashboard for the packages you care about across npm, PyPI and crates.io. It pulls download history, releases, dependents and GitHub stars/PRs, and flags whether traffic looks like real use vs. bots/mirrors — all live in your browser. Nothing is sent anywhere; your list is stored locally on this device.
One per line (or comma/space separated). Prefix the ecosystem: pypi:requests, crates:serde. A bare name = npm.
Aliases: py:/pip: → PyPI, cargo:/rs: → crates.
Scoped npm works (@scope/name); versions are ignored.
Or upload a .txt. Change the list anytime via ⚙ Settings.

Tracked packages
Edit the full list (this replaces what's tracked). Prefix ecosystems: pypi: / crates: (bare = npm).
Popular thresholds
A package counts as Popular if it meets any of these:
dependents > stars > downloads/day >
Saved in this browser's local storage only. (downloads/day = last-30-day total ÷ 30)
