Hi, Alexis
10 SQLite connections are included in Valentina Server Free license.
Complete license agreement can be found here:
http://valentina-db.com/docs/dokuwiki/v6/doku.php?id=valentina:licensing:valentina_server_license_agreement
As you can see, there are some restrictions for commercial usage.
In short:
* Commercial usage of the Valentina Server Free is possible only in the internal network. Web apps, accessible from the internet, can't use it as well.
* And it is impossible for developer to include Valentina Server (or Valentina Server Free) into own installer, distribute own license file. For such case Valentina Server Embedded should be used.
