Raven

Raven is a Linux runtime for running Windows applications without a virtual machine or Wine. It runs the Windows program code directly on the CPU inside a sandbox and answers its system calls by implementing Windows-kernel and service behavior, including processes and threads, files, the registry, windows, and input. Graphics are routed through Wayland and Vulkan, with DXVK and vkd3d-proton providing Direct3D support. Applications are installed with their normal Windows installers into separate prefixes, each with its own C: drive and registry. Raven supports both 32-bit and 64-bit programs, Windows Installer, NSIS and Inno Setup packages, selected .NET Framework versions, and Direct3D 8 through 12 through its graphics components. It is currently built from source for x86_64 Linux using CMake, C++20 and Python 3.11 or newer. Raven's Linux runtime is licensed under GPL-3.0-or-later, while its guest adapters and imported components retain their stated licenses.

Rune is a native UI framework written in Rust that renders interfaces on the GPU. It includes its own renderer, text engine, layout system, and spring-based animations, and targets macOS, Windows, Linux, and the web from one codebase. Applications can run headlessly, allowing a coding agent or other scripted process to render screens to PNG, inspect the element tree, and drive controls with scripted input. The project is pre-release, uses an MIT license, and is developed by Anomaly.

Winc is a desktop code editor developed by DEEIX AI, written in Rust with its own CPU rasterizer and rendering engine. It provides multiple cursors, find and replace, syntax highlighting, lightweight go-to-definition and usage lookup without a language server, whole-file formatting through external tools, and previews for Markdown, images, SVG, XLSX, and CSV files. Its Git interface supports side-by-side and word-level diffs, hunk staging, commits, pushes, a commit graph, and blame; it also includes a project file tree, .gitignore-aware search, and an integrated terminal. Winc runs on macOS, Linux, and Windows, and is distributed through platform packages, portable archives, and GitHub Releases under the Apache License 2.0.

Rabbet is a from-scratch C++ 3D game engine with a sparse-set entity-component system, versioned entity handles, dense component pools, and a system-and-resource runtime. Its OpenGL 4.1 renderer provides a forward path with metallic-roughness PBR, a Phong fallback, lighting and shadow maps, emissive surfaces, optional image-based lighting, post-processing, CPU particles, and heightmap or noise terrain. The Forge editor provides a dockable ImGui workspace around a render-to-texture viewport, asset thumbnails, hierarchy reparenting, click-to-pick, snapping gizmos, and Play/Pause/Step/Stop controls that snapshot and restore scenes. Assets use stable UUIDs and .import sidecars; models, textures, audio, materials, shaders, prefabs, and scenes are supported, with scenes stored as readable JSON. Lua behaviors run through sol2 with live hot-reload and inspector-editable fields, while physics uses Jolt rigidbodies and audio uses miniaudio. The repository includes the engine, editor, examples, and tests, including the Orb Hunt demo game. It uses CMake 3.24 or later and a C++20 compiler, supports macOS and Linux, fetches pinned dependencies during configuration, and is licensed under Apache License 2.0.

Vorssaint is a free, open-source Swift/SwiftUI macOS menu bar toolkit that combines utilities including per-application volume and audio controls, output and microphone switching, system monitoring, network statistics, app and window switching, window snapping, Dock previews, clipboard history, text snippets, file staging, screen capture, display and energy controls, media tools, cleaning, and app removal. It is modular: users can install or remove complete features, with removed features stopping loading while retaining their settings for later reinstallation. The toolkit also provides configurable shortcuts, panels, a command bar, and optional bundles for common setups. Vorssaint runs locally without an account, analytics, tracking, subscription, or required network service; its volume mixer requires no audio driver or setup, and selected features request only the relevant macOS permissions, including accessibility, screen recording, audio recording, microphone, camera, calendars, notifications, and disk access.
