Why You Can't Use Redis® on Windows in Production

Technical articles and news about Memurai.

Redis, known for its lightning-fast performance and versatile data structures, has become the de facto standard in modern application development that requires a fast in-memory database. However, when it comes to deploying Redis in a production environment on Windows, challenges and limitations are all but gone. Don’t get me wrong, there are ways, but they’re not ideal.

In this article, I'll delve into the reasons why using “Redis for Windows” for production might not be the best idea, and explore a dedicated solution like Memurai that offers a compelling alternative.

So let’s get going!

Challenges and Limitations

Redis was initially designed with Unix-like systems in mind, and for many years, the thought of using Windows as a hosting environment simply wasn't realistic. Eventually, the "Redis for Windows" project, backed by Microsoft, tried to bridge the gap between both worlds, delivering a reliable and stable version of Redis that you could run on your Windows servers.

The Legacy of Redis on Windows & MSOpenTech

Redis, born in a Unix-centric ecosystem, has consistently struggled with Windows compatibility. This incompatibility is so pronounced that even the official Redis documentation steers users towards the Windows Subsystem for Linux. Acknowledging the gap, Microsoft embarked on a porting journey under MSOpenTech, striving to align Redis with Windows. Despite this endeavor, the project was abandoned seven years ago upon aligning with Redis 3.0, rendering it obsolete for contemporary demands.

This discontinuation created a security and compatibility vacuum for users needing Redis on Windows. Numerous alternatives and forks sprouted in the quest to bridge this gap, but their success was constrained. Most could only boast compatibility up to Redis 5.0, excluding the significant enhancements and security fortifications embedded in later Redis versions. Although some forks purported synchronization with more recent Redis versions, apprehensions regarding their stability and security robustness echo loudly, leaving users in a lurch, navigating the intricate maze of Redis on Windows.

Problems with Redis for Windows

In other words, while there is a project that, at some point, provided a reliable and stable version of Redis that was Windows-native, after 7+ years of that project being dead, the reality is completely different. The two major issues with this version of Redis are:

  • Lack of security updates: Considering this project's been dead for almost a decade, it hasn't received any security updates over the last few years. In fact, it's so dead that security scanners are no longer checking for it. It's probable that the only people looking for instances of this Redis version are hackers, so that should tell you something.
  • Lack of modern Redis features: The Redis for Windows version stayed at version 3.0 (with a pre-release version 3.2), which means almost all the useful and new features added by Redis during its latest major version update (think of TLS support, for example), will not be accessible for you.

The Need for a Dedicated Solution like Memurai

We all know that tailored software solutions always perform better and offer a superior experience for their users when compared to generic or ported versions. While Redis shines brilliantly in its natural habitat of Unix-like systems, the complexities introduced when attempting to transplant it onto the Windows environment require a more specialized approach; it's not enough to say magic words like "Docker" or "WSL2.0" and hope everything works out of the box. And as we already saw, the only "stable" version of Redis for Windows is just too old and outdated to even be considered a realistic option. This is where Memurai steps onto the stage as a dedicated solution that understands the intricacies and nuances of Windows, offering a range of benefits that make it the only choice for your production environment.

Native Windows Compatibility

Memurai doesn't merely function on Windows; it thrives on it. By capitalizing on native Windows mechanisms and APIs and years of troubleshooting and maintenance, Memurai brings a fresh native solution to the table. This native compatibility translates into a harmonious coexistence with your existing Windows-based ecosystem, resulting in an integration that feels seamless and natural.

Enhanced Performance and Stability

The core of Memurai's design philosophy centers around delivering the kind of performance and stability that's expected in production environments. By taking advantage of Windows-specific features, Memurai optimizes its operations for the Windows platform. This optimization translates into improved responsiveness, reduced latencies, and enhanced overall performance. With Memurai, you can bid farewell to the performance degradation that might accompany attempting to shoehorn Redis into an environment it was not originally intended for.

A Bridge Between Redis and Windows

Memurai doesn't aim to replace Redis; it seeks to bridge the gap between the Redis ecosystem and the Windows landscape. It's a solution that respects the conventions and requirements of both worlds. This means that developers and technical decision-makers can harness the power of Redis without relinquishing the reliability and familiarity of the Windows environment. In fact, at the time of this writing, the latest version of Memurai is fully compatible with Redis 7, which translates to a seamless user experience when devs try to migrate their less-than-optimal workarounds to a new Memurai installation.

Professional Support and Future-Proofing

Adopting Memurai is not merely about finding a workaround for Redis' incompatibility with Windows; it's about embracing a future-proof solution that ensures your Redis-powered applications stay resilient and reliable over time. Memurai is backed by a team of experts who offer professional support, ensuring that any challenges you encounter are met with swift resolutions. Moreover, regular updates and maintenance releases keep Memurai aligned with the ever-evolving Windows landscape, providing peace of mind for your production infrastructure.


While Redis may have established its supremacy in the * nix world, its seamless integration into the Windows environment remains a task better suited for specialized solutions like Memurai.

With its native compatibility, optimized performance, and commitment to bridging the gap between Redis and Windows, Memurai offers technical decision-makers and developers a pragmatic path forward. With the MSOpenTech project remaining frozen in time, Memurai thrives, continuously evolving and improving to provide a robust, secure, and fully supported Redis experience on Windows.

By choosing Memurai, you're not merely adapting; you're thriving, leveraging the full potential of Redis without compromise, and ensuring a future where your Windows-based infrastructure stands on the shoulders of a solution tailor-made for success.
