X-chromosome testing is included in 23andMe's personal genomic service and deCODE genetics' offerings. Family Tree DNA launched an X-chromosome matching service for their Family Finder test in January 2013. FTDNA also offer two panels of X STR testing.
Gedmatch provides a free tool for the comparison of X-chromosome data which can be used to compare results from all the different companies.
