SparkyFitness is a self-hosted health-tracking platform with a backend, web interface, and native iOS and Android apps. Individuals and families can record nutrition, exercise, hydration, sleep, fasting, mood, and body measurements, then review trends in charts and reports. It can also synchronize data from several health and fitness services while keeping the main data store under the user's control. The project is under active development, and some releases may introduce breaking changes; AI chat and family access are still beta features.

Awesome Gaussian Skills combines a searchable knowledge base of hundreds of 3D Gaussian Splatting, NeRF, and graphics methods with a set of focused agent skills. Researchers can use it to read papers, compare techniques across multiple dimensions, review implementations for known bug patterns, plan experiments, migrate NeRF ideas to 3DGS, or bridge CAD, mesh, and Gaussian representations. Each skill is a standalone SKILL.md package for compatible agents.

Awesome Codex Skills organizes practical skills across development, productivity, communication, data analysis, and utility categories, often with a short use case and installation command. The catalog mixes skills stored in the repository with links to external projects, so it is useful for discovery but each item’s permissions, dependencies, and quality still need separate review.

SkillHub gives organizations a self-hosted place to publish, discover, install, and manage reusable agent skills. Packages can use semantic versions and release tags, while team namespaces define membership, roles, visibility, and publishing policies. Review gates and audit logs support governed internal sharing behind an organization's firewall.

Exam Cram Coach organizes slides, notes, assignments, and past papers into a chaptered knowledge base and provenance-labeled quiz bank. It adapts tutoring, drills, mistake review, and cheat-sheet preparation to the learner's starting point and available time, while marking material-backed claims, AI supplements, and unsupported questions separately. Basic text and Office ingestion uses standard tooling, but some PDF and visual artifact routes require optional local dependencies.

Bring domain guides, specialist-agent instructions, and multi-step workflows from the Claude Code ecosystem into Google Antigravity's skill format. The vault spans software development, infrastructure, security, and business work, but Antigravity loads metadata for every installed skill at session start, so targeted installation is recommended over adding the entire collection.

Thaw is a menu bar manager for macOS 26 and macOS 27. It can place items in hidden or always-hidden sections, reveal them through hover, an empty-area click, scrolling, or swiping, and automatically hide them again. Users can also reorder items by dragging, search the menu bar, adjust spacing, save layout profiles, or show hidden items in a separate bar for notched displays. The app is available as a release download or through Homebrew, but its stated platform support targets the newer macOS generations rather than older systems.

Moonlight PC receives game or desktop streams from NVIDIA GameStream or Sunshine hosts across Windows, macOS, Linux, Steam Link, and several ARM devices. It supports hardware-accelerated H.264, HEVC, and AV1 decoding, HDR, 7.1 audio, keyboard shortcut forwarding, and multiple gamepads. AV1 specifically requires Sunshine and a supported GPU on the host.

ImageGlass is a cross-platform desktop viewer for quickly navigating more than 90 image formats, including WEBP, JXL, SVG, HEIC, AVIF, HDR, and RAW files. Version 10 supports Windows, Apple silicon Macs, and Linux. The Classic edition is free and updated manually, while the paid Microsoft Store edition includes a seven-day trial and automatic updates.

node-hid is a native Node.js module for enumerating, opening, reading from, and writing to USB or Bluetooth HID devices through synchronous or asynchronous APIs. It supports common Windows, macOS, and Linux environments, with prebuilt binaries for many Node.js and Electron combinations. Less common targets may need a source build, and operating systems often restrict access to keyboards, mice, or devices that emulate them; Linux may also require udev rules.

Open CoDesign is a local-first desktop app that turns prompts into interactive prototypes, slide decks, and marketing assets, with live preview, pinned comments, and targeted visual adjustments. It supports Claude, GPT, Gemini, Kimi, GLM, Ollama, and OpenAI-compatible providers, and can import existing Claude Code or Codex configurations. Projects can be exported as HTML, PDF, PPTX, ZIP, or Markdown. Cloud providers require the corresponding API key or subscription, while a local model can support offline use.

Mac Sai is a free, open-source macOS utility for cleaning system junk and browser data, finding duplicates, fully uninstalling applications, visualizing disk space, and scanning for malware. It offers one-click scans without subscriptions, ads, or telemetry and installs through Homebrew or a DMG. Release builds are signed with an Apple Developer ID and notarized, which is especially relevant for an app that requests broad file access.

QQ Chat Exporter saves direct and group conversations as HTML, JSON, TXT, or Excel while also downloading associated images, videos, and stickers. Reading and parsing are performed on the user's computer rather than through a project-hosted server. Windows users can choose a packaged installer, Windows and Linux support a shell workflow, and Docker deployment is available across macOS, Linux, and Windows. Apple Silicon systems run the relevant Docker component through Rosetta.

Deep Code CLI is a terminal coding assistant optimized for deepseek-v4. Run deepcode in a project to use adjustable reasoning depth, conversation resume, code or chat undo, image pasting, Agent Skills, and MCP integrations; its settings can also be shared with the VS Code extension. Other OpenAI-compatible models are supported, but the harness, tool constraints, and context behavior are designed primarily around DeepSeek.

Frappe Books is an open-source desktop accounting application for Windows, macOS, and Linux, built around double-entry bookkeeping. It handles invoices, bills, payments, journal entries, and point-of-sale activity, stores financial data in a local SQLite file for offline use, and produces reports including the general ledger, profit and loss statement, balance sheet, and trial balance.

Ice helps Mac users hide, automatically rehide, search, and drag menu bar items into organized sections, including a separate bar that works well around a display notch. It also offers shortcuts and appearance controls for tint, borders, shadows, and menu bar shapes. The app is still under active development and supports only macOS 14 or later.

BeeCount is a local-first personal bookkeeping app with multiple ledgers and accounts, budgets, recurring entries, tags, reports, and bill import or export on Android and iOS. It works without cloud configuration, while users who need synchronization can choose iCloud, Supabase, WebDAV, S3, or the self-hosted BeeCount Cloud web service. AI chat, OCR, and voice can assist entry capture, and MCP requires BeeCount Cloud; personal use is free, but commercial use requires a license.

Shuorenhua is a Chinese-first rewriting skill for chats, status updates, READMEs, release notes, forum posts, and longer writing. It identifies the scene and protects facts such as numbers, versions, commands, paths, quotations, names, and responsibility assignments. It then chooses rewrite strength, fixes structural patterns before word substitutions, and performs a fidelity check for facts, terminology, and register. An annotation mode can flag issues without rewriting. It supports several agents and explicitly excludes code, logs, configuration, and command output.
