What is a Package Name Checker?

A package name checker is an essential tool for developers, app creators, and software teams to validate the uniqueness of their chosen package names before publishing apps or libraries. Whether you're releasing a mobile app on the Google Play Store or publishing a JavaScript package to the npm registry, having a unique package name is crucial to avoid naming conflicts and ensure a smooth deployment process.

Our tool helps you instantly check if a package name is already taken or if it's available for your next project. Simply enter your desired name, and we’ll return accurate results within seconds. This prevents issues with app store policies, versioning systems, and user confusion caused by duplicate or similar names.

The Package Name Checker is built with developers in mind — it’s fast, free, and easy to use. You don’t need to navigate through multiple sites or do manual checks anymore. From mobile apps and web projects to internal tools and open-source libraries, this tool works across use cases and platforms.
