Compared head to head
Looking for an alternative to
Open-source licenses
- Permissive: 8. Use it anywhere, including in closed products. You keep the copyright notice; Apache-2.0 also grants patent rights.
- Strong copyleft: 5. If you distribute the program or anything built on it, you must release the whole source under the same license.
- Network copyleft: 2. Like GPL, and running a changed version as a web service counts as distributing it, so its users get the source too.
- Weak copyleft: 1. Changes to the licensed files must be shared, but you can link them into a closed program.
