Mousiki is a keyboard-driven terminal music player (TUI) for browsing and playing local music files or searching and streaming online tracks through yt-dlp. It provides word-by-word synchronized lyric highlighting, an FFT spectrum visualizer, waveform rendering, spinning-disk artwork, and queue controls for shuffling, repeating, and track management. Colors, animations, visualizer behavior, hotkeys, and local music paths are configured through a file in the user's home configuration directory. It has native support for Linux, macOS, and Android through Termux; Windows support is unverified. Building requires CMake, a C++17 compiler, FFmpeg, yt-dlp, and the Python syncedlyrics package, and the project is licensed under Apache License 2.0.

mirador is an open-source terminal dashboard built with Rust and ratatui for keeping in a terminal tab and glancing at throughout the day. It provides configurable panels for world clocks, a calendar and agenda, weather, an editable task list, notes, a market watchlist, a calculator, RSS news feeds, and live CPU and network charts; panels can be enabled, rearranged, focused, and edited through keyboard controls. Tasks, notes, and the watchlist are stored as hand-editable TOML files rather than in a database or sync service. The dashboard uses keyless public endpoints for weather and market data and configurable RSS feeds for news; the project states that it requires no account, API key, or telemetry and does not contact external services unless requested.

Audio-Cassette-Simulation is a set of local Bash scripts that uses FFmpeg to simulate cassette-tape audio profiles. It applies tape noise, wow and flutter pitch modulation, bandwidth limits, and equalizer adjustments through presets for BASF LH Extra C90, Maxell UD C90, Sony CHF60 and CHF90, TDK D90, and Soviet MK-60 tape. The scripts convert local MP3, OGG, M4A, and AAC files, or record a live web stream into segmented files, saving processed output in an `out` directory. It requires FFmpeg compiled with libmp3lame and is licensed under the MIT License.

tmux is an open-source terminal multiplexer that creates, accesses, and controls multiple terminals from a single screen. A session can be detached while its terminals continue running in the background, then reattached later, allowing terminal-based processes such as coding agents to survive disconnection. It runs on OpenBSD, FreeBSD, NetBSD, Linux, macOS, and Solaris, and is built from source with dependencies including libevent and ncurses.

TrueDeck is a terminal-first multi-agent coding workbench for running several coding agents on the same repository in separate live terminal panes. It supports agents including Grok, Codex, Cursor, Claude, and Gemini while retaining their native command-line interfaces rather than presenting them in a chat webview. It provides split panes, tabs, focus control, and workspace restoration, with repository-specific and global memory plus MCP and project-context synchronization handled in the background. Installers and portable builds are distributed through the project's GitHub Releases, and the repository is licensed under the MIT license.
