What is Open Source License Generator?

Choosing a license decides how others can use your code — and it is a must-do step for every open source project. This generator covers the 7 most popular licenses: MIT (the permissive default), Apache-2.0 (with patent grant), GPL-3.0 (strong copyleft), BSD-3-Clause, ISC, MPL-2.0 (weak copyleft), and Unlicense (public domain). Pick a license, enter the copyright holder and year, and get a complete, standards-compliant LICENSE file you can copy or download instantly. Short descriptions help you understand the trade-offs.

▶FAQ7 questions
What is an open source license generator?

An online tool that creates LICENSE files. Input: license type (MIT, Apache-2.0, GPL-3.0, BSD-3-Clause, ISC, MPL-2.0, Unlicense), copyright holder name, and year. Output: a standards-compliant LICENSE file. Used before open-sourcing a project. This tool is not legal advice.

Which license is the most popular?

MIT is the most popular permissive license — anyone can use, modify, and distribute your code freely as long as they keep the copyright notice.

What is the difference between GPL and MIT?

GPL is copyleft: derivative works must be open-sourced under the same license. MIT has no such requirement and allows closed-source use.

Is the generated license legally binding?

The text is based on official license templates, but this tool is not legal advice. Consult a professional for important projects.

Can I use these licenses commercially?

Yes. Permissive licenses like MIT, Apache, BSD, and ISC all allow commercial use. GPL allows it too, but derivatives must stay open source.

Which license types are supported?

7 in total: MIT, Apache-2.0, GPL-3.0, BSD-3-Clause, ISC, MPL-2.0, and Unlicense (public domain).

Can I edit the generated text?

Yes, it is plain text you can edit. Note that modifying official license templates may change their legal effect.
