You can sign up by clicking on the button "Start for Free" or "Start Free Trial" and see how much GlassFrog costs on our pricing page.
For the Premium version you have the option to select your own currency clicking on "change currency" to see how much the cost per user per month converts to you.
Please note that GlassFrog pricing is prorated, meaning you only pay for the users that are part of your organization, starting from the day they join. If you add a user toward the end of a billing period, you only pay for time used, not for the entire month. There is also the option to add viewer accounts who will not be counted as paying users. More info here about viewer accounts.
Billing occurs on the 1st of each month. Feel free to add users at any time. You only pay for time used.
