When Open Source Turns Closed: The Redis Rebellion That Shook the Internet

In early 2024, a pivotal moment unfolded in the open-source software world when Redis Inc. changed the licensing model for its widely used in-memory data store, shifting from the permissive BSD-3 license to the more restrictive RSAL and SSPL licenses. This move effectively barred major cloud providers like AWS, Google Cloud, and Microsoft Azure from offering managed Redis services without paying licensing fees, triggering widespread backlash from the developer community and tech giants alike. The change was seen as a betrayal of open-source principles, prompting a coalition of major tech companies and open-source advocates to create Valkey, a community-driven fork of the last BSD-licensed version of Redis. Dubbed ’Fossilized Redis,’ Valkey aims to preserve the software’s legacy as truly open source, ensuring free and unrestricted use for all, including commercial cloud services. The split has created a dual ecosystem: one path led by Redis Inc., pursuing a sustainable commercial model with official support and innovation, and another led by Valkey, relying on community collaboration and institutional backing to maintain technical parity. The conflict highlights a growing tension in the tech industry between the idealism of open-source collaboration and the economic realities of sustaining large-scale software development. Developers and enterprises now face strategic decisions—whether to adopt the licensed version for stability and support or embrace the open fork for freedom and cost efficiency. The outcome of this divide has far-reaching implications, setting a precedent for how other open-source projects might navigate monetization without alienating their user base. As Valkey continues to evolve with contributions from major players and the broader community, its success will depend on sustained engagement, technical competitiveness, and resistance to fragmentation. Meanwhile, Redis Inc. must prove that its paid model delivers sufficient value to justify the cost in a market where a free alternative exists. This episode marks a turning point in the evolution of open source, testing whether decentralized communities can successfully challenge corporate control over foundational technologies. The ripple effects are already being felt across the software industry, with other open-source projects closely monitoring the situation as they consider their own licensing futures. Ultimately, the Redis saga underscores a fundamental question: can the ethos of shared innovation survive in an era of increasing commercialization? The answer will shape the architecture of the internet for years to come, influencing everything from startup agility to cloud competition and the long-term accessibility of critical digital infrastructure.
