free, open-source software

Wagn is licensed under the GNU General Public License (version 2 or later).

"Free" means you're not trapped.  You're not trapped paying the licensers every time you want a change.  You're not trapped by the whims of the licenser's hosting and pricing policies.  You're free.  Also, you don't have to pay.

"Open-source" has become a transparency slogan, but it has a specific meaning with software.  The "source" is the code that humans can read.  If you buy "closed-source" software, you can't see anything readable, so you never really know how it works.  That means technical users can't fully customize and improve it.  We're proud of our code; we want people to see it, and we thank the many generous developers who help make Wagn better.
