CIQ launches C3 compatibility catalogue for Rocky Linux

CIQ has launched C3, a free public compatibility catalogue for Rocky Linux and its enterprise distributions.

The service is designed to give hardware vendors, independent software vendors, AI platform providers, developers and community contributors a single place to verify and publish whether their products work with Rocky Linux, RLC Pro, RLC Pro AI and RLC Pro Hardened.

CIQ, the founding support and services partner of Rocky Linux, says the catalogue addresses a need among vendors and enterprise customers to check compatibility with specific Rocky Linux-based products rather than rely on a broader Enterprise Linux assumption.

Three tiers

C3 has three levels of assurance. Community Compatibility is open to anyone in the Rocky Linux ecosystem at no cost, allowing vendors to self-attest and publish compatibility findings in the public catalogue.

The second level, Vendor Verified, is for software companies, hardware suppliers and AI platform providers that want a more formal validation process. The third, CIQ Certified, is for organisations and vendors seeking formal certification.

CIQ is positioning the resource for both technology vendors and the enterprise teams that buy and deploy their products. In practice, procurement and IT departments can use the catalogue as a reference when assessing operating system support for servers, software packages and AI infrastructure.

That is particularly important in environments where support and validation influence purchasing decisions, especially in sectors running specialist hardware or regulated workloads. For customers deploying security-focused operating systems or systems tuned for AI and high-performance computing, compatibility checks often need to go beyond whether a product runs on a…
