Frequently Asked Questions
What is a viral license?
Viral licenses like GPL require you to open-source your entire project if you include even one GPL-licensed dependency. Our tool detects these automatically.
Can I use this for commercial projects?
Yes! The tool is completely free and helps you understand which licenses allow commercial use and which don't.
How accurate is the detection?
We use SPDX license identifiers and multiple detection methods to ensure high accuracy. Always consult with legal counsel for final decisions.
Do you store my code?
No. We only analyze license information from your dependency files. Your code never leaves your browser.
