I got tired of discovering mid-project that a package hadn't been touched in years. deathwatch scans your package.json and/or requirements.txt and flags deps that are dead, suspicious, or healthy before they become a problem. bashnpm install -g deathwatch deathwatch It checks last publish date, weekly download count (flags if under 100/week), and deprecated notices on npm. PyPI support too. Everything is color-coded in the terminal, no config needed. Tune sensitivity with flags: bashdeathwatch --threshold 12 --warn 6 Source: https://github.com/davitotty/deathwatch npm: https://www.npmjs.com/package/deathwatch
