Show HN: Free CLI Tools – Zero Dependencies, MIT Licensed

https://workspace-ivory-one.vercel.app/
2•a_m73110•1h ago
I built 59 single-file CLI tools because I was tired of: - pip install hell for simple tasks - Leaving terminal to use web converters - Writing "quick scripts" that took 2 hours

Everything is zero-dependency Python. Copy, paste, run.

Highlights: • HTML → Markdown converter (with article extraction) • JSON formatter with validation • Port scanner with banner grabbing • Password generator with entropy analysis • Duplicate file finder (saved me 40GB) • Git repo health analyzer • SSL certificate inspector • 52 more...

All MIT licensed. No signup. No dependencies.

Live: https://workspace-ivory-one.vercel.app Repo: https://github.com/barrowryan89-cloud/pd-researcher (currently mirroring to Vercel)

Would love feedback on which tools you'd actually use.
