Recently updated open-source projects

CrossOver adds a transparent, movable crosshair above games on Windows, macOS, and Linux. Choose from its built-in reticles or drop in a custom PNG, SVG, or GIF, then adjust position, size, color, opacity, and multi-monitor placement. It can also pin several markers at once. Compatibility is not universal: most games need windowed or borderless-fullscreen mode, Vulkan titles may not render the overlay, and a few games reject or flag crosshair-overlay software.

RocketSim extends Xcode’s iOS Simulator with tools for inspecting behavior, debugging interfaces and network activity, checking accessibility, and producing screenshots or recordings. Developers can trigger app actions and repeat test flows from the desktop app, while the RocketSim CLI and companion agent skill enable state-aware automation that inspects the visible UI before tapping, typing, or swiping. It is built specifically for iOS developers working with the Simulator rather than for general device automation.

Edit Mind watches a video library, transcribes audio, analyzes frames, identifies faces and objects, and builds a vector index so users can find specific videos or scenes with natural-language queries. The self-hosted version runs through Docker and processes data locally. It remains under active development and is explicitly not production-ready.

Kanri is a desktop Kanban app for Windows, macOS, and Linux that works without an account or internet connection. It supports customizable columns and cards, rich descriptions, subtasks, due dates, tags, Trello import, and granular or full exports for backup. Board data is stored in a single local JSON file, and built-in cloud synchronization is intentionally excluded, making it suitable for users who want to keep control of their own data.

appify generates a real macOS `.app` bundle around a terminal UI command, giving tools such as btop or weechat their own window, Dock icon, and Cmd+Tab entry. Run it with the target command and optionally set the application name, icon, bundle identifier, working directory, window size, or bundled Ghostty configuration. Generated apps embed their own GPU-accelerated Ghostty terminal engine, so users do not need an existing Ghostty installation. The tool is specifically for macOS rather than a cross-platform app packager.

Reactotron is a desktop debugger for React and React Native applications on macOS, Linux, and Windows. It can display application state, API requests and responses, logs, global errors, and quick performance benchmarks, while also subscribing to or replacing selected state. The integration is added as a development dependency and is not included in production builds.

ShadowEditor is a self-hosted 3D scene editing system available through web and desktop interfaces. It manages scene assets such as models, materials, audio, and animation, while adding user and role controls, history, autosave, and real-time playback. It is aimed at teams that need managed scene assets rather than a lightweight local-only editor, and deployment relies on its server component and MongoDB.

Lepton uses GitHub Gists as a desktop snippet library for macOS, Windows, and Linux, organizing public or secret entries with tags, language groups, and search. It can render Markdown and Jupyter Notebook content, supports custom themes, and works with GitHub tokens as well as GitHub Enterprise.

Reframed combines screen capture and editing in one macOS application. It records a display, window, region, or connected iOS device with system audio, microphone, and an optional webcam overlay, then opens the result directly in a timeline editor. Users can trim tracks, reduce microphone noise, generate captions, and add cursor-following zooms before exporting MP4, MOV, or GIF files with configurable resolution, frame rate, and platform presets.

Apple Notes Exporter moves an entire iCloud or On My Mac notes library into formats such as Markdown, PDF, DOCX, JSONL, or ENEX while retaining folder hierarchy, rich content, and attachments. Exports can be run from the macOS interface, a scriptable command-line tool, Apple Shortcuts, or the bundled MCP server, and incremental mode rewrites only new or modified notes. The app requires macOS 11 or later and Full Disk Access. Notes stored in Gmail, Outlook, Yahoo, or other email accounts must first be moved into iCloud or On My Mac.

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.

Wora is a cross-platform desktop player for organizing and listening to a local music collection. Users can create playlists, play FLAC, WAV, and common audio formats, start tracks quickly through a command menu, and view synchronized or unsynchronized lyrics. Ready-made releases are available, and the project can also be built for Linux, macOS, and Windows. Development is moving to a new Tauri-based version, so the current repository accepts only critical fixes and has limited room for normal feature contributions.

ClaudeMeter shows five-hour session usage, seven-day usage, and Sonnet-specific limits in the macOS menu bar, with color-coded icons, pacing warnings, configurable threshold notifications, and automatic refresh. It can import a Claude session from local browser cookies or accept a session key manually, stores that credential in Keychain, and exports usage percentages as JSON for status-line scripts or dashboards. This is an unofficial client that accesses Claude’s web API through browser authentication; the project warns that this may violate Anthropic’s terms and could affect the account.

Venice Skills packages the Venice API into separate, on-demand Agent Skills for authentication, chat, Responses, embeddings, image generation, image editing, and other surface areas. Each folder contains a `SKILL.md` that an agent runtime can load when the corresponding endpoint is needed, and the catalog is maintained alongside the API specification. You can install the full `skills` directory or only selected folders into Claude Code, Codex, Cursor, Hermes, and compatible hosts. This is instruction material for agents, not a standalone Venice client.

agr treats agent skills like project dependencies for teams. It installs skills from Git repositories or local directories into detected AI tools, records the desired set in `agr.toml`, and pins exact versions in `agr.lock` so teammates can reproduce the same environment with one sync command. Users can also upgrade skills deliberately or run one temporarily with `agrx` without adding it to the project configuration.

Pennywise opens web pages and media in a small always-on-top window that can be resized, repositioned, and made partially transparent. A detached mode lets pointer interactions pass through to the window underneath, which is useful for tutorials, dashboards, reference pages, or videos while working. Builds are available for macOS, Windows, and Linux, but the project is no longer maintained, so users should verify compatibility with current operating systems and websites before relying on it.

SPAN Finder is a Windows file manager built around macOS-style Miller columns, so users can see the current folder, its parents, and the next destination at once. It adds multi-tab and split views, Quick Look previews, batch renaming, Git status, remote FTP/SFTP connections, and restorable workspaces. It requires Windows 10 version 1903 or later; crash reporting is enabled for exceptions only and can be disabled in settings.

Auto-News collects RSS feeds, Reddit posts, tweets, YouTube videos, web articles, and personal journal notes into a Notion-based reading workflow. It uses OpenAI, Gemini, or Ollama models to filter unwanted items, generate insights, create weekly recaps, and turn takeaways into tasks. The open-source setup is self-hosted and has meaningful infrastructure requirements: the documented minimum is 2 CPU cores, 6 GB of memory, and 20 GB of disk.
