Compared head to head
Looking for an alternative to
Open-source licenses
- Strong copyleft: 2. 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.
Languages
PHP 2, Ruby 1, CSS 1 and Go 1.
