Package Typosquatting Checker

Paste npm or PyPI package names and catch typosquats before they reach your dependency tree, scored locally by edit distance and confusables.

This tool is in beta

Still being tested. If a result looks wrong, tell us.

Report a problem

Paste package names to score them.

The scoring is heuristic and the popular list is a fixed snapshot bundled with this page, so a brand new package or a small library is invisible here and a clean name is not proof of safety. A finding means the name reads like a popular package; it is a reason to look twice before installing, not a verdict about anyone's intent. Nothing is installed, downloaded, or sent anywhere.

Names to check

EcosystemEach ecosystem checks its own popular list

Package names

One per line, up to 200

Names stay under 214 characters each (npm's own limit) and the whole paste under 50,000 characters. Every check runs in this tab; no registry is contacted.
