HiveMQ comes with a perpetual license for the currently available version. Included is our basic software and support subscription for one year. As long as the subscription is valid, all major/minor updates and bugfix releases are available at no extra cost. Extending the subscription or switching to extended support (phone support, emergency patches and support hours up to 24/7) is possible anytime.
Please provide us the following information and we will contact you soon to discuss your use case.
