Question 1

Which open source license should I choose?

Accepted Answer

For maximum freedom and simplicity, MIT or ISC are the most popular permissive licenses. Apache 2.0 adds an explicit patent grant. GPL-3.0 is copyleft — anyone using your code must also open source theirs. MPL-2.0 is a weak copyleft middle ground. Unlicense releases code into the public domain.

Question 2

Where do I put the generated LICENSE file?

Accepted Answer

Place the LICENSE (or LICENSE.txt / COPYING) file at the root of your repository. GitHub and most platforms automatically detect it and display the license name on your project page.

Question 3

Do I need to keep the license header in each source file?

Accepted Answer

Permissive licenses (MIT, BSD, ISC) only require the notice in the LICENSE file. Copyleft licenses (GPL, AGPL, MPL) recommend adding a short copyright header comment at the top of each source file. This tool provides the recommended header for copyleft licenses.

Question 4

Is my information sent anywhere?

Accepted Answer

No. All license templates are bundled in the page and the generation happens entirely in your browser. Your name and project details never leave your device.
