As with every software, you will sooner or later reach a point where you can’t progress on your own anymore. For this reason we offer you multiple ways of support to help get your work done!
Apart from the licensing options, we also offer:
To get your developers up-to date with the latest developments of Blaze-Persistence and internal workings
To help you with issues in your project remotely or on-site
If you want specific bugs to be fixed or features to be implemented faster you can sponsor development by buying and assigning sponsoring hours to specific issues
