RunCat Neo

BongoCat is a native animated desktop companion that reacts to keyboard, pointer, and gamepad input. It is built in C and C++ with SDL3 and OpenGL, supports Windows, macOS, and Linux, and processes keyboard and mouse input locally rather than recording or uploading it. The runtime uses platform-specific input listeners, an atomic input queue, an SDL3 main loop, model-parameter updates, and OpenGL composition for the pet window and overlays. It includes built-in model assets and supports external model sources, including Mver packages, Tauri sources, `.model3.json` files, and image patches. Live2D rendering uses the Cubism SDK when available; without it, the project builds a diagnostic backend. The source code and native runtime are licensed under AGPL-3.0-only, while the default model mode and bundled model assets have separate MIT licensing.

lolcat is a command-line utility that prints terminal output with a colored gradient. It supports configurable gradient settings and an animation mode that renders output line by line. The project is distributed for Linux through Snap and for macOS through Homebrew.

macOS is a proprietary, Unix-based desktop operating system developed by Apple Inc. for Mac computers. It is built on the Darwin (XNU) kernel and provides the Aqua graphical environment with native application frameworks such as AppKit, Cocoa, and SwiftUI, a POSIX-compliant user space, and services including iCloud, Handoff, and the Mac App Store for app distribution. macOS runs on Intel x86_64 and Apple silicon (ARM64) architectures with support for Universal binaries, includes security features like Gatekeeper and System Integrity Protection, and is licensed and distributed by Apple as part of Mac hardware and system updates.

Tinycast is a free, open-source macOS launcher built with SwiftUI and AppKit. It provides fuzzy app launching, global and per-app hotkeys, Spotlight-based file search, searchable clipboard history, inline calculations and conversions, quicklinks, Apple Shortcuts, Markdown snippets, shell commands, window and system actions, calendar meeting access, notes, emoji search, and optional AI chat and text actions. The application can run existing Raycast extensions, rendering them as native SwiftUI, and supports importing and exporting settings from Raycast. It has no third-party dependencies, Electron runtime, or telemetry; clipboard content and snippet keyword matching are handled locally. Tinycast is distributed through Homebrew or release DMGs and is licensed under AGPL-3.0.

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.
