Get to know Qt License Server
Qt License Server is centralized solution for managing license verification and reservations across all Qt Group products. It authenticates users, validates product licenses, manages license reservations and provides detailed usage reporting and statistics.
Designed for scalability, Qt License Server supports Named, Pool and Floating license models, ensuring flexibility for organizations with multiple teams.
Qt License Server is available in two deployment options:
- Cloud-hosted by Qt for effortless setup and maintenance
- On-premises deployment for customers who prefer full control over their infrastructure
Cloud Server Hosted by Qt
On-Premise Server hosted by Customer
Qt License Service (daemon on workstations)
The Qt License Service is a lightweight background process that manages license reservations on your workstation, ensuring your Qt and Qt Quality Assurance tools stay properly licensed.
It securely communicates with the Qt License Server to reserve, validate and automatically renew licenses. In case of a network interruption, the service continues operation using cached license data until the connection is restored.
The service is installed automatically with the Qt Online Installer but can also be installed manually, for example on build servers or custom environments.
