About this tool

IconVault's npm Name Checker checks many npm package names at once, so you can pick a name with confidence before you publish. Paste one name per line and it queries the live npm registry for each: a 404 response means the name is available, anything else means it is taken. Results appear row by row with clear available, taken and error states, and you can copy the available names straight to your clipboard.

The tool is free with no signup. One honest note: the checks run against the live npm registry, so each lookup is a quick network request, and a name that is free right now could be registered by someone else before you publish. When a name matters to you, publish a placeholder version soon or reserve your namespace with an npm scope.
