The story of Keycloak—a powerful open-source identity and access management tool—illustrates the complex interplay between open-source ideals and corporate interests. Originally developed by Red Hat and released under the permissive Apache 2.0 license, Keycloak became a cornerstone for secure, seamless single sign-on (SSO) systems used by businesses worldwide. Its community-driven model allowed startups and enterprises alike to build robust authentication systems without reinventing the wheel. However, in 2019, IBM’s acquisition of Red Hat triggered widespread concern among developers and businesses relying on Keycloak. While the software remained legally open source, the shift in governance and Red Hat’s increasing emphasis on commercial offerings like Red Hat Single Sign-On created fears of vendor lock-in, reduced community influence, and potential prioritization of proprietary features. This perceived erosion of neutrality sparked a quiet but significant response: some organizations began maintaining internal forks of Keycloak for greater control, while others migrated to alternative open-source solutions such as Authentik and Zitadel. These projects, though not direct forks, gained traction by emphasizing transparent governance and independence from large corporate stewards. The Keycloak situation highlighted that open-source sustainability involves more than licensing—it hinges on trust, community engagement, and the balance between commercial viability and collaborative ethos. As digital identity becomes increasingly central to online security and user experience, the decisions made during this period continue to influence how organizations approach identity management. The outcome wasn’t a collapse of Keycloak, which remains actively developed and widely used, but rather a diversification of the ecosystem, with businesses now more cautious about dependency on corporately backed open-source projects. This evolution underscores a broader lesson: in the digital age, the infrastructure enabling our daily online interactions is shaped not just by code, but by human values, strategic decisions, and the ongoing tension between openness and control. The legacy of Keycloak’s journey is a more resilient, pluralistic identity landscape—one where choice, caution, and community vigilance play critical roles in preserving the integrity of our digital lives.
