Handy is a free, open-source, offline speech-to-text desktop application built with Tauri (Rust backend + React/TypeScript frontend). It records microphone audio, transcribes using local ASR models (Whisper, Parakeet, etc.), and pastes the text into any active application via global shortcuts. The architecture is a monolith with a single-process Rust backend that manages audio capture, VAD (Silero), model loading (GGUF/ONNX), transcription engines (transcribe-cpp, transcribe-rs), clipboard paste, system tray, and recording overlays. The frontend is a React SPA that communicates with the backend via Tauri commands and events, providing a rich settings UI, model management, onboarding, history, and post-processing via OpenAI-compatible LLM APIs or Apple Intelligence. The codebase exhibits high craftsmanship with extensive use of RAII guards, lock-free streaming, state machines, platform-specific abstractions, and thorough error handling. It is actively maintained with frequent commits, a large community, and cross-platform builds for macOS, Windows, and Linux, including Nix support.
ReinaManager is a desktop application for managing visual novel game libraries, built with Tauri 2 (Rust backend) and React 18 (TypeScript frontend). It provides a comprehensive suite of features including game metadata aggregation from multiple sources (VNDB, Bangumi, Hikarinagi, DLsite, ErogameScape, YMGal, Kungal), game launch and process monitoring with playtime tracking, save data backup/restore, a download and installation pipeline, collection management with drag-and-drop, and cloud synchronization of play status. The architecture follows a clean separation between frontend and backend: the React frontend communicates via typed Tauri IPC through a service layer, while the Rust backend uses SeaORM with SQLite for persistence. The metadata system employs a source adapter pattern for extensibility, and the application is cross-platform (Windows, Linux) with platform-specific optimizations for game launching and monitoring. The codebase is under active development with frequent releases and demonstrates strong engineering practices including a well-structured migration system, a standalone segmented download engine, and a robust OAuth flow.
