Our verdict on YARP

YARP, or Yet Another Reverse Proxy, is an open-source .NET toolkit for developers building customizable HTTP reverse proxy applications. It fits teams working with ASP.NET Core that need to integrate proxy behavior into an application rather than adopt a separate hosted reverse-proxy service. The toolkit supports HTTP reverse proxying and direct forwarding, with configuration for routes, clusters, and destinations. It runs across Windows, Linux, and macOS through the .NET platform.

Its main strength is the breadth of proxy controls available within one developer-focused toolkit. Published capabilities include load balancing, destination health checks, session affinity, request and response transforms, WebSocket and SPDY proxying, TLS termination, output caching for proxied responses, and route-level rate limiting. These features give teams room to shape traffic handling around application requirements instead of relying only on fixed proxy behavior. Configuration can be provided from files or programmatically, and integration is available through the Yarp.ReverseProxy NuGet package for ASP.NET Core applications.

YARP is best suited to developers who want a customizable, self-hosted reverse proxy built into a .NET application and who can manage that deployment model. Its scope is broader than basic forwarding because it combines traffic distribution, health checks, affinity, transforms, caching, and rate controls. However, teams looking for a ready-to-run hosted service should choose a different type of product, since YARP is a library and toolkit that must be integrated and operated within an application environment. It is also a less natural fit for organizations that do not build on ASP.NET Core or the .NET platform.
