It&#x27;s $150 per 50 users per month. You can use our hosting or get it installed on your server (Debian) for the same price. We have around a hundred paying customers in Poland of various size, one in USA. The biggest implementation is 10k users every day, around 200 tables. So it scales well. If interested drop me a line, agsamek at Gmail.<p>And BTW - the system works in English and has some documantation inlined in Schema Editor. We will also do English docs. In the meantime we will provide you with good human support :)
