In the Cloud Native era, apps are complex, interconnected & data driven. Reactive programming is a useful paradigm for any system that has to deal with things happening, and solves the problem of extracting intelligent signals from the noise of modern data volumes.

Reactive Extensions for .NET was created in 2008 by the Cloud Programmability team at Microsoft, for a Cloud Native future, which has now arrived

The System.Reactive NuGet package has been downloaded over 150 million times, and is used by Visual Studio, .NET Interactive and ReactiveUI.

Since 2023, the Open Source project has been maintained by endjin.

Reactive programming provides clarity when our code needs to respond to events. The Rx.NET libraries were designed to enable cloud-native applications to process live data in reliable, predictable ways.

We've written a FREE book which explains the vital abstractions that underpin Rx, and shows how to exploit the powerful and extensive functionality built into the Rx.NET libraries.

Reaqtor evolves Rx.NET by adding state & durability primitives to enable long running queries, for processing live or historic data streams. Reaqtor is used by Bing, MSN, and M365 to handle billions of standing stateful queries, processing thousands of events per second.

We spent 5 years collaborating with Microsoft to Open Source Reaqtor under the .NET Foundation and become the project maintainers.

We share the value we create.

We help our customers succeed by leveraging our Intellectual Property.

"Past Us" created value so that "Future Us" could benefit, and work smarter; constantly focusing on delivering real business value rather than reinventing the wheel, to scratch a technical itch. You can benefit from our efforts too.

How .NET 9.0 boosted JSON Schema performance by 32%

How .NET 9.0 boosted JSON Schema performance by 32%

Matthew Adams

We benchmarked endjin's JSON Schema library on .NET 9.0 and saw large performance gains. There are even more gains to be had with new System.Text.Json features.

How .NET 9.0 boosted AIS.NET performance by 9%

Ian Griffiths

.NET 9.0 has shipped, and for the fourth year running, we benchmarked endjin's AIS.NET library and were very happy to see substantial performance gains, with no extra work required.

We pride ourselves on our customer relationships. Here's what they had to say about us.

I asked our Cloud Solutions Architect from Microsoft to recommend a lean, hands-on & opinionated firm to walk with us & challenge us on our Azure journey. He recommended endjin & they were great.

Endjin had the experience to build our cloud strategy, to take Watchfinder global.

With a rapidly growing market share for our SaaS NEC Contract Management Tool, we increased R&D investment and focused on reviewing our principle architecture. Endjin assisted in re-modelling strategic elements of our technical roadmap in parallel to streamlining our DevOps procedures, providing future readiness, increased efficiency, to support our exit to the thinkproject group.

When we selected Microsoft Azure to run business critical, client facing web applications in the financial services sector, endjin provided us with the day-to-day in-depth expertise we needed to keep our software & hosting environment relevant, reliable & robust.

Endjin helped us step into the modern era. We've gone from worrying about operating servers, to focusing our efforts on being Fintech innovators.

Endjin helped us to find the performance bottlenecks in our WPF based application running on XenApp clusters. They quickly identified bottlenecks and suggested changes to mitigate the issues. Endjin upskilled our team so we can now do the analysis and optimisation ourselves. Endjin delivered beyond our expectations.
