FAQ
What data sources do you use?
We pull data from the npm registry, Bundlephobia for bundle sizes, and the OSV/Snyk databases for known CVEs and security advisories.
Can I analyze a full package.json at once?
Yes. Paste your entire package.json and we'll analyze every dependency in one go, giving you a prioritized list of the highest-cost packages.
How is the maintenance score calculated?
We look at last publish date, open issues ratio, commit frequency, and whether the package has active maintainers to produce a single health score.
