Compared head to head
Open-source licenses
- Permissive: 17. Use it anywhere, including in closed products. You keep the copyright notice; Apache-2.0 also grants patent rights.
- Strong copyleft: 9. If you distribute the program or anything built on it, you must release the whole source under the same license.
- Network copyleft: 4. Like GPL, and running a changed version as a web service counts as distributing it, so its users get the source too.
Languages
TypeScript 5, JavaScript 5, Go 4, Rust 3, PHP 3, Python 2, C# 2, Dart 1, Objective-C 1, Ruby 1, Shell 1, Svelte 1 and Elm 1.
