The product has open-source and commercial licenses; the open-source version is under GPL. Commercial licensing adds advanced security, custom reasoning and inference, high-availability replication, and professional support. The maker describes fine-grained attribute-based access controls and lists encryption at rest as a commercial feature. Deployment options include Linux/Unix, Docker, Windows, and macOS installations, as well as on-premises/BYOL, AWS, and Azure. The maker lists data integration, governance, knowledge management, data productization, and AI-driven customer support as typical uses. Personal, Developer, and Project workstation licenses cost $99.99 as a one-time purchase, $199, paid once, and $499, paid once, respectively. OpenLink Software, the privately held maker, was founded in 1992.
