Pricingpretalx is open source software, which means you can host your own instance without paying a dime … apart from your time, and your nerves, and the server costs, that is.
You can instead choose to use our hosting service here at pretalx.com, as a range of other events already do.
Apart from our usual standard rate for events, we also offer a reduced price for community events. Community events are those events that don't aspire to make a profit, are run by community volunteers, and aren't backed by a company. This cheaper price is made possible by the professional rate, for events backed by a professional company. There is feature parity between both of these packages.
