Which license should I choose?

MIT and ISC are the most permissive. Apache 2.0 adds patent protection. GPL 3.0 requires derivative works to stay open-source. BSD variants are similar to MIT with slight differences. Unlicense puts your code in the public domain.

Is this license generator free?

Yes. Free forever, no account required. Runs 100% in your browser.

What file should I save it as?

Save as LICENSE (no extension) in the root of your repository. GitHub auto-detects it.

Can I use a different year?

Yes. The year field defaults to the current year but you can change it to any year.

No. Everything runs in your browser.
