Once you have downloaded JXRay, started it for the first time and registered your copy, your free trial period starts. It lasts for 30 days or 7 tool runs, whichever comes first. After the trial period ends, you have a choice between purchasing a permanent license or continue running JXRay in pay-as-you-go mode.


Please read the license agreement. A single-user license is granted to one person, and allows only that person to use no more than one copy of the JXRay Memory Analyzer at any time. Once you make a payment, you will receive an e-mail from with your license key. Please note that all payments are non-refundable.

If you don’t plan to use JXRay frequently, you can pre-pay a small sum and then use that money every time you run JXRay. It is required that your machine is connected to the Internet and is able to reach our license server. The money on your account never expires. When you use JXRay in pay-as-you-go mode, you are bound by the same single-user license agreement as above. Click one of the buttons below to add money to your JXRay pay-as-you-go account. Each successful run currently costs $1. Make sure that when you fill out the form, you specify the same email that you used to register your copy of JXRay! That email is associated with your JXRay account. Please note that all payments are non-refundable. If you have any questions, please contact us at
