We highlight three support levels

depending on project phase, time constraints and budget

Free Support

All Jmix developers are backed by a free forum and there is ample knowledge there already. We always try to answer each new question quickly but the speed heavily depends on staff availability and difficulty of the question. Many questions are also answered by fellow community members.
