About this tool

Publishing code without a licence leaves others legally unsure whether they can use it. This generator produces the text of the common open-source licences — MIT, Apache 2.0, GPL v3, BSD and the Unlicense — with your copyright holder and year filled in, and helps you compare what each permits, requires and limits.

Choosing a licence is a real decision: permissive ones like MIT and Apache let others do almost anything, while copyleft ones like GPL require derivative works to stay open. Seeing the permissions, conditions and limitations side by side helps you pick the one that matches your intent before you generate the file.

It runs in your browser, so it is instant. Add the generated LICENSE file to your repository so contributors and users know exactly what they may do with your code.

Frequently asked questions

Which licences can it generate?
MIT, Apache 2.0, GPL v3, BSD and the Unlicense, with your copyright holder and year inserted.
What is the difference between permissive and copyleft licences?
Permissive licences (MIT, Apache, BSD) allow almost any use with minimal conditions; copyleft licences (GPL) require derivative works to be shared under the same terms. The tool compares these so you can choose.
Why does my project need a licence?
Without one, others have no clear legal permission to use, modify or distribute your code. A licence states exactly what is allowed.
Is this legal advice?
No. It generates standard licence texts to help you choose and apply one; for complex situations consult a professional.
