    OpenNetMeter

    OpenNetMeter

    A simple program to monitor your network/data usage

    OpenNetMeter is a Windows desktop application intended for monitoring network traffic and data usage at the system and per-process level. It features a user-friendly interface that displays upload and download speeds in real time, along with a history of data consumption for the current session, and aggregates totals since launch or last reset. The app also breaks down usage by process, giving you visibility into which applications are consuming network bandwidth. It lives in the system tray, making it accessible and minimally intrusive for everyday use. Since it's open-source, users can inspect how data collection is done and trust that it’s not sending data elsewhere. While still evolving, it serves a practical niche for users who want more transparency than what built-in OS tools provide.

    Bedrock Framework

    Bedrock Framework

    High performance, low level networking APIs

    Bedrock Framework is a set of low-level .NET networking APIs for building high-performance custom servers and clients. Its architecture focuses on transport-agnostic communication so protocols are not tightly coupled to a specific network mechanism. Builder APIs provide structured ways to configure client and server pipelines. The core package includes middleware and transports for sockets and in-memory communication. A separate experimental package contains protocol and transport implementations that may eventually move into the main framework. The project builds on connection abstractions introduced in ASP.NET Core for client-server communication. It is primarily intended for developers creating specialized networking stacks where performance, protocol control, and composability matter.
