Suggestions for low cost online Card Sort tool?

Eric Adler Totally agree that IA is incredibily important for a positive user experience. As this is so important companies know that most times companies will pay through the nose for it and sometimes that is a tough sell to the people that pay the bills 😃!

Having said that, I have been lucky to work with clients who paid for Optimal Sort which is the best tool in my opinion. But I have also had clients who did not want to foot the bill. So ... 

If you can do them in person and have access to a Mac, I would recommend https://xsortapp.com/ as its free and has analytics built in.  

If you have to do it remote, I would suggest using something like Trello. You have to do the analytics manually but it would cost you nothing. http://niawdeleon.com/how-to-use-trello-for-card-sorting/. 

But if you can afford $25 for a month (for most projects that's enough for 1 test) you could get https://www.provenbyusers.com/pricing.php or https://www.usabilitest.com/pricing. That $25 is money well spent just for the reports!

Anyways ... good and keep fighting the UX fight!
