Name: Akka.NET
Author: Petabridge

Akka.NET is an open source implementation of the actor model in C# and F# and it's helped tens of thousands of .NET developers solve concurrency, streaming, state machine, and real-time application problems since 2013. Akka.NET works in applications of any size, whether it's embedded systems at the edge or global scale SaaS products.

How Actors Process Work

Actors are self-contained processes that communicate exclusively through messages. Here's how a loan application flows through an actor system — no shared state, no locks, fully concurrent.

How actors process a loan application — fan-out, gather, behavior switching

Actors fan out work concurrently, gather results, and switch behavior — no locks, no shared state

We Created the Framework

Petabridge created and maintains Akka.NET. We depend on Akka.NET being a popular choice for .NET developers in order to remain in business. That means we're responsive to user suggestions, ship bug fixes fast, and are easy to get ahold of.

Whether you need help getting started, want expert guidance on a production system, or need hands-on implementation support, we're here.

// WHY_AKKA.NET

Why Choose Akka.NET?

Foundation Built from robust, global-scale patterns originally implemented on the JVM. The original Scala Akka powers Twitter, Walmart, Blizzard, and more. We inherit all of those lessons learned from billions of production-hours.

Versatile Not just for giant cloud apps. Akka.NET runs inside mobile and desktop applications for concurrency, streaming, and state management — and scales up to distributed clusters on Kubernetes. Bring it to any project.

Support Free and open source, supported by Petabridge. We depend on Akka.NET being popular to remain in business. We're responsive to user suggestions, bug reports, and easy to reach on Discord.

Performance A single actor can process 7–8 million messages per second. Systems routinely run millions of actors per machine. Akka.NET is designed for speed at scale.

Customization Akka.NET doesn't hold strong opinions on how you wield it. We treat users like competent adults — a stark contrast to more opinionated frameworks.
