Package Name Generator

When this tool helps

Draft a reverse-domain application identifier when starting an Android or Flutter project. Choose a domain you control and a stable app name before publishing.

How to use this tool

Enter a domain followed by an application name, such as example.com shopping. Use a domain you control for a published app, and review the result before setting a permanent application ID.

A worked example

Input

example.com shopping

Expected result

com.example.shopping

Enter a simple two-part domain followed by an app name, separated by a space. This utility reverses the first two components and appends the remaining components; it also normalizes characters into identifier-like segments.

Edge cases and limitations

• This is a simple formatter, not a public-suffix parser. Multi-part domains such as example.co.uk and subdomains need manual review.
• Do not paste a full URL with a protocol, port, or path. Use the domain and application name only.
• An Android application ID and a source-code package can differ. Renaming an identifier in a live app has consequences beyond renaming a source folder.

Use the result in your app

For Android, review the applicationId and namespace in the generated Gradle file. For Flutter, use the organization prefix in the generator and inspect the platform identifiers after creating native runners.

Keep your workflow private

This utility processes input only in this tab. It does not upload or persist pasted content. Review generated output before using it in a production application.
