Harmony
Patching, replacing and decorating .NET and Mono methods
Harmony gives you an elegant and high-level way to alter the functionality in applications written in C#. It works great in games and is well established in titles like 7 Days To Die, BattleTech, Besiege, Cities:Skylines, Kerbal Space Program, Oxygen Not Included, Ravenfield, Rimworld, Sheltered, Stardew Valley, Staxel, Subnautica, The Ultimate Nerd Game, Total Miner, Unturned, SCP: Secret Laboratory and many more. If you develop in C# and your code is loaded as a module/plugin into a host application, you can use Harmony to alter the functionality of all the available assemblies of that application. Where other patch libraries simply allow you to replace the original method, Harmony goes one step further. It is also used in unit testing WPF controls and in many other areas. Installation is done by using 0Harmony.dll in your project or by using the Lib.Harmony nuget package. -

StabilityMatrix
Multi-Platform Package Manager for Stable Diffusion
StabilityMatrix is a project that helps organize, evaluate, and compare generative AI models and their behavior across prompts, datasets, or configuration settings. It provides a framework to run experiments systematically—capturing inputs, model configurations, outputs, and metrics—so researchers and practitioners can reason about differences in quality, robustness, and failure modes. The repository often bundles tooling for automated prompt sweeping, scoring heuristics (such as diversity, coherence, or task-specific metrics), and visualization helpers to make comparisons interpretable. This approach is useful for model selection, prompt engineering, and benchmarking new checkpoints against baseline models under reproducible conditions. By turning ad-hoc tests into tracked experiments, StabilityMatrix reduces bias, surfaces subtle regressions, and accelerates iteration when tuning generative systems. -

Wasabi Wallet
Open-source, non-custodial, privacy focused Bitcoin wallet for Windows
Wasabi is an open-source, non-custodial, privacy-focused Bitcoin wallet for desktop, that implements trustless coinjoin. Wasabi creates trustless coinjoin transactions over the Tor anonymity network. The coinjoin coordinator cannot steal from, nor breach the privacy of the participants. Coinjoin is a mechanism by which multiple participants combine their coins (or UTXOs, to be more precise) into one large transaction with multiple inputs and multiple outputs. An observer cannot determine which output belongs to which input, and neither can the participants themselves. This makes it difficult for outside parties to trace where a particular coin originated from and where it was sent to (as opposed to regular bitcoin transactions, where there is usually one sender and one receiver). Coinjoin can be applied multiple times, and as many transactions are grouped together, participants may save on transaction fees. Coinjoin is the preferred method of gaining privacy in the Bitcoin network. -
