Run macOS actions through predictable nested key sequences instead of search.
Project overview
Leader Key lets macOS users press a chosen leader shortcut followed by nested key sequences to launch applications, control media, manage windows, or run commands. Actions are defined in its configuration and can also be triggered through URL schemes from Alfred, Raycast, shell scripts, or Keyboard Maestro. The project remains free and open source, but its author says development focus has moved to the successor application Tuna, which includes Leader Key functionality.
Sync clipboard content across computers and browsers over your local network.
Project overview
CrossPaste synchronizes text, images, files, and other clipboard formats across Windows, macOS, and Linux devices. A Chrome extension can join the same clipboard mesh. Data is stored locally and shared over the LAN with end-to-end encryption, while the built-in OCR extracts text from images on-device without sending screenshots to an external service.
Live Helper Chat is an open-source, self-hostable support application for websites, with web and mobile clients for teams of operators. Integrations add voice, video, screen sharing, Telegram, Facebook Messenger, and WhatsApp through Twilio, while its bot system can connect to third-party AI services. Installing from source requires PHP 8.2 or newer, and some multimedia features depend on external services.
Use Notion through an unofficial multi-tab desktop client focused on Linux.
Project overview
Lotion wraps Notion in an unofficial desktop application with multiple tabs, themes, spell checking, and desktop integration. Its primary audience is Linux users who want a dedicated Notion workspace rather than another browser window, although macOS and Windows builds are also published. The macOS release is unsigned and may trigger Gatekeeper warnings, while Windows support is described as best effort, so users on those platforms should expect extra setup or rough edges.
Monitor traffic, domains, IPs, and proxy nodes across gateways.
Project overview
Neko Master is a self-hosted dashboard for collecting and analyzing network traffic from one or more OpenClash backends. It presents real-time connections and trends by time range, domain, IP address, ASN, geography, and proxy node, with a bilingual web interface that can also be installed as a PWA. Deployment is available through Docker, but the dashboard depends on reachable gateway backends or deployed agents to supply the traffic data it visualizes.
Manage Microsoft To Do tasks with a keyboard-focused desktop client.
Project overview
Ao is an unofficial desktop client for Microsoft To Do on Windows, macOS, and Linux. It emphasizes fast keyboard operation with extensive local shortcuts, configurable global shortcuts, direct list navigation, quick task creation, and search. Theme choices, compact mode, scalable UI, and an always-available window make it useful for people who prefer a dedicated task app, but it is a community project rather than an official Microsoft client.
Practice piano scales, chords, and fifths with MIDI, keyboard input, and quizzes.
Project overview
Piano Trainer turns scales, chords, and the circle of fifths into interactive desktop exercises. Learners can respond with a MIDI keyboard or the computer keyboard, then reinforce recall through quizzes, hard mode, and shuffled practice. Free cross-platform builds are available. It works best as a hands-on reference and repetition tool for self-paced learners rather than as a complete structured piano course.
JustHireMe is a cross-platform, local-first workbench for ingesting job leads, ranking them with profile-aware rules and vector matching, and tracking applications in a local CRM. It can generate tailored resumes, cover letters, and outreach materials, while browser-based automatic application remains experimental rather than part of the stable core. The first launch downloads its runtime pack, and the macOS build is not yet notarized.
IPFS Companion is a browser extension for Chromium-based browsers and Firefox that connects everyday browsing to a locally running Kubo node. It can handle ipfs:// addresses, redirect content-addressed sites and file paths to the local gateway, and provide quick actions for importing, pinning, unpinning, and copying CIDs or public gateway links. A local node must be running through IPFS Desktop or the command-line daemon.
Manage local or remote rclone storage and transfer tasks through a desktop interface.
Project overview
Rclone UI gives rclone users a cross-platform desktop interface for managing remotes and transfer tasks instead of working mainly from the command line. It can connect to rclone RCD instances running locally or on another server, making it useful for personal machines and homelabs. Windows, macOS, and Linux builds are available; remote setups still require users to configure network access and authentication safely.
Manage a local music library with a simple cross-platform player
Project overview
Museeks is a focused desktop player for Linux, macOS, and Windows, with support for common formats including MP3, M4A/AAC, FLAC, WAV, and OGG. It refreshes the library automatically and includes playlists, queue management, shuffle, loop, cover art, speed control, a sleep blocker, and M3U import or export. Official installers come from the releases page; community package-manager builds may lag behind.

Track daily tasks with a completion meter and automatic resets.
Project overview
todometer is a desktop to-do app that makes daily progress visible through a completion meter. Users can add, pause, complete, delete, and reorder tasks, with optional daily resets, notifications, and reminders. A local REST API, MCP server, and custom URL protocol also allow scripts, shortcuts, or AI assistants to add and control tasks outside the main window.
Run measurements, signal generation, and logging with Pocket Science Lab hardware.
Project overview
PSLab App connects to Pocket Science Lab open hardware over USB and turns a phone or computer into an experiment control and data collection interface. The device can act as an oscilloscope, waveform generator, frequency counter, programmable voltage or current source, and data logger. The app spans mobile, desktop, and web, but the core experiments require PSLab hardware.
Capture, edit, annotate, and export screenshots or recordings on macOS.
Project overview
BetterShot is a local-first macOS menu-bar app for region, window, and full-screen capture, screen recording, OCR, and color picking. Its floating preview opens an editor for annotations, backgrounds, padding, shadows, cropping, and video trimming, with MP4 export and drag-to-app workflows; it uses no cloud service, subscription, or telemetry.
Manage and synchronize local agent skills across many AI coding platforms.
Project overview
skills-manage is a local-first desktop app that keeps a central skill library and installs selected skills into Claude Code, Codex, Cursor, Gemini CLI, and many other platforms through symlinks. Users can inspect skill contents, discover project-level libraries, import from GitHub, browse marketplaces, organize collections, and batch-install them. Current prebuilt packages are limited to Apple Silicon macOS and are not notarized; other platforms must run from source. GitHub PATs and AI API keys are stored in the local SQLite database without encryption at rest.
Aggregate coding-agent sessions and delegate work across multiple agents.
Project overview
Codeg brings sessions from Claude Code, Codex, OpenCode, Gemini CLI, and other coding agents into one workspace. A primary agent can delegate parts of a task to independently running sub-agents, while built-in Git worktree flows support parallel development. The workspace also includes project scaffolding and live Office document editing. It can run as a desktop application, a standalone server, or a Docker deployment, but the underlying agents and their local credentials or configuration are still required.
Label images, text, audio, video, and documents in one interface.
Project overview
Universal Data Tool is a web and desktop application for editing and annotating mixed datasets. It supports workflows such as image classification or segmentation, named entities, audio transcription, video annotation, document review, and general data entry. Use the hosted interface, install the desktop build, or deploy it on premises, with real-time collaboration available in the labeling workspace. Projects can be exchanged through the UDT CSV or JSON formats and embedded into a React application.
Run online OneNote in a dedicated desktop app with isolated account tabs.
Project overview
P3X OneNote places the online OneNote experience in a dedicated desktop process instead of a permanent browser tab. It supports system-tray operation and multiple isolated tabs for personal or corporate Microsoft accounts, with per-tab labels, ordering, pinning, and zoom settings. The application remains a wrapper around Microsoft's online service, so it is not a separate offline note database.
