    STranslate

    STranslate

    A ready-to-go translation ocr tool developed with WPF/WPF

    STranslate is a lightweight, open-source machine translation front end that lets users translate text between languages using a variety of supported back-end translation engines or APIs, offering a simple GUI for quick translation tasks without needing to write code or use complex web UIs. The application is designed to be small, cross-platform, and flexible, giving users the ability to type or paste text and receive instant translations while optionally selecting the desired language pairs or switching between multiple service providers. By abstracting backend complexity, STranslate makes it easy for both casual users and developers to get translations in local apps, offline modes (where supported), or even integrate translation workflows into larger projects via plugins or scripting hooks. It often includes features like clipboard monitoring, keyboard shortcuts, history tracking, and configurable translation preferences that enhance daily productivity.

    ArchiSteamFarm

    ArchiSteamFarm

    C# application with primary purpose of farming Steam cards

    ASF is a C# application with the primary purpose of farming Steam cards from multiple accounts simultaneously. Unlike Idle Master which works only for one account at a given time, while requiring Steam client running in the background and launching additional processes imitating "game-playing" status, ASF doesn't require any Steam client running in the background, doesn't launch any additional processes and is made to handle unlimited Steam accounts at once. In addition to that, it's meant to be run on servers or other desktop-less machines and features full cross-OS support, which makes it possible to launch on any operating system with .NET Core runtime, such as Windows, Linux, and macOS. ASF is possible thanks to the gigantic amount of work done in the marvelous SteamKit2 library. Today, ASF is one of the most versatile Steam power tools, allowing you to make use of many features that were implemented over time.

    Microsoft Authentication Library .NET

    Microsoft Authentication Library .NET

    Microsoft Authentication Library (MSAL) for .NET

    MSAL.NET (Microsoft.Identity.Client) is an authentication library that enables you to acquire tokens from Azure AD, to access protected Web APIs (Microsoft APIs or applications registered with Azure Active Directory). MSAL.NET is available on several .NET platforms (Desktop, Universal Windows Platform, Xamarin Android, Xamarin iOS, Windows 8.1, and .NET Core). The MSAL library for .NET is part of the Microsoft identity platform for developers (formerly named Azure AD) v2.0. It enables you to acquire security tokens to call protected APIs. It uses industry-standard OAuth2 and OpenID Connect. The library also supports Azure AD B2C. Acquiring a token interactively enables the application to acquire a token after authenticating the user through an interactive sign-in. There are specificities, though depending on the platforms (Xamarin Android, Xamarin iOS, or UWP)

    Unity MCP

    Unity MCP

    AI-powered bridge connecting LLMs and advanced AI agents

    Unity-MCP is an open-source integration that connects artificial intelligence assistants with the Unity game development environment through the Model Context Protocol. The project enables AI tools such as coding assistants and autonomous agents to interact directly with Unity projects, allowing them to analyze scenes, modify assets, and generate code within the development environment. By exposing Unity editor functionality through MCP tools, the plugin allows external AI systems to understand the structure of a game project and manipulate it programmatically. Developers can use natural language prompts to instruct AI assistants to create objects, modify scenes, or generate gameplay scripts automatically. The system supports both editor-level automation and runtime integration, meaning AI models can also be used inside compiled games for dynamic behavior such as interactive characters or debugging tools.

    App Metrics

    App Metrics

    App Metrics is an open-source and cross-platform .NET library

    App Metrics is an open-source and cross-platform .NET library used to record metrics within an application. App Metrics can run on .NET Core or on the full .NET framework also supporting .NET 4.5.2. App Metrics abstracts away the underlying repository of your Metrics for example InfluxDB, Prometheus, Graphite, Elasticsearch etc, by sampling and aggregating in memory and providing extensibility points to flush metrics to a repository at a specified interval. App Metrics provides various metric types to measure things such as the rate of requests, counting the number of user logins over time, measuring the time taken to execute a database query, measuring the amount of free memory, and so on. Metrics types supported are Apdex, Gauges, Counters, Meters, Histograms, and Timers. Support Push and Pull based metrics collection via TSDB-specific reporting extensions and exposing metrics in the required format over HTTP.

    Foundatio

    Foundatio

    Pluggable foundation blocks for building distributed apps

    Pluggable foundation blocks for building loosely coupled distributed apps. Includes implementations in Redis, Azure, AWS, RabbitMQ and in memory (for development). When building several big cloud applications we found a lack of great solutions (that's not to say there aren't solutions out there) for many key pieces to building scalable distributed applications while keeping the development experience simple. Wanted to build against abstract interfaces so that we could easily change implementations. Wanted the blocks to be dependency injection friendly. We were initially using an open-source Redis cache client but then it turned into a commercial product with high licensing costs. Not only that but there weren't any in-memory implementations so every developer was required to set up and configure Redis. We initially looked at NServiceBus (a great product) but it had high licensing costs (they have to eat too) and was not OSS friendly.

    reko

    reko

    Reko is a binary decompiler

    Reko (Swedish: "decent, obliging") is a decompiler for machine code binaries. This project is freely available under the GNU General Public License. The project consists of front ends, core decompiler engine, and back ends to help it achieve its goals. A command line, a Windows GUI, and a ASP.NET front end exist at the time of writing. The decompiler engine receives inputs from the front ends in the form of either individual executable files or decompiler project files. Reko project files contain additional information about a binary file, helpful to the decompilation process or for formatting the output. The decompiler engine then proceeds to analyze the input binary. Reko has the ambition of supporting decompilation of various processor architectures and executable file formats with minimal user intervention. For a complete list, see the supported binaries page.

    MSI Downloader

    MSI installers for a wide range of software and utilities

    MSI Downloader has been created for IT professionals who want a quick and easy method of downloading the latest MSI installers for various software. MSI installers are much easier to use for deployment using systems like Group Policy, Microsoft Deployment Toolkit (MDT) and Microsoft System Center Configuration Manager (SCCM). Some publishers happily supply MSI installers for their software, however, some are very hard to find. So this new tool will not only be providing the easy to find MSI installers, but also the hard to find ones and in some cases, the impossible to find ones - ones where we will create the MSI installers for them! The aim to keep all the MSI Installers within our utility fully up to date, but if you find something that is not, please let us know and we will correct it.
