Scan your stack from the terminal

changelogradar-check reads your local package.json, calls the public scan endpoint, and prints the verdict — the same blast-radius scan, in your shell. Every run ends with the one thing the CLI can't give you: your live Sunset Calendar.

# In any project with a package.json:
npx changelogradar-check

# ✔ Read 22 dependencies
# ● Breaking      3   (next, react, twilio)
# ▲ Deprecation   4
# $ Price-change  2   (2 vendors raised prices)
# 🔒 9-date Sunset Calendar → https://changelogradar.the-atlas-project.net

No install, no signup

npx runs it once; nothing is stored, nothing leaves but dependency names and versions.

Same archive as the web scan

The CLI hits the same server-side matcher — the verdict is identical to pasting your package.json on the site.

CI-friendly

Exit non-zero on Breaking changes to fail a build early, or just print the summary. Wire it into your pipeline.

The CLI is a distribution artifact — every run carries the footer back to the full scan. Prefer a GUI? Paste your package.json on the homepage.
