Kayako user reviews
"Delivers an unrivalled customer support experience". Once the most popular PHP-based self-hosted helpdesk app in the world, now offers a hosted version as well. Used by huge organizations like General Electric, FedEx and NASA.
Nice set of features, great customer support. But it\'s expensive AND they have changed their pricing model without notice! It was around $500 one-time for the self-hosted version, now they made that version unsupported and force to upgrade to $2000 PER USER!!!!
