A self-hosted messaging platform engineered for real-time, distributed systems.
Download · Platform · Clients · Documentation
BarkFluff pairs native clients with a gRPC-first .NET backend. Clients discover their service endpoints through Beacon, receive live changes through streaming updates, and communicate with independent services that can evolve and scale without turning the product into a distributed tangle.
Windows, Android, and macOS release builds. Other clients are available from source below.
One entry point. Beacon gives clients one trusted way to discover the platform; Configuration supplies the service registry and runtime settings.
Independent product services. Identity, profiles, messaging, files, presence, calls, bots, federation, and more run as focused .NET services, with CQRS and MediatR where they fit.
Real-time by default. The Updates service uses persistent gRPC streams for live product events, while RabbitMQ carries asynchronous work between services.
Built to operate. PostgreSQL stores state, Redis serves hot data, MinIO handles objects, and Docker runs the stack. Native and web clients are built with Kotlin, WinUI, SwiftUI, Qt, and web technologies.
