Find the open-source solution that fits.

AriaNg Native turns the AriaNg interface into a Windows and macOS desktop application, so aria2 tasks do not need to live in a browser tab. Users can create downloads by dropping files or URLs, inspect torrent contents before starting, and open torrent, metalink, or magnet links through desktop associations. Tray support and local file operations make it better suited to persistent desktop use.

Add focused skills for Vue 3 Composition API and Options API work, Vue Router, Pinia, component and end-to-end testing, JSX, debugging, and adaptable composables. You can install the bundle or selected skills, and explicitly asking the agent to use a Vue skill improves activation reliability; the maintainer labels the project an early community experiment whose guidance may be incomplete or inaccurate.

Elasticvue is an open-source graphical client for managing Elasticsearch data and cluster state. It is available as a desktop app, browser extension, hosted web app, or self-hosted deployment. Users can view a cluster overview, manage indices, aliases, and shards, search or edit documents, and run REST queries. Web and Docker-based use generally require Elasticsearch CORS configuration, while the desktop app needs less cluster-side setup.

Paper2Any converts papers, images, text, or a topic into editable scientific figures, technical roadmaps, draw.io diagrams, and PPTX decks, with chat-based revision for supported outputs. It also covers workflows such as rebuttal drafting and layout-preserving PDF-to-PPT conversion. Running the open-source version requires its Python, graphics, document-conversion, and model dependencies; the hosted Studio and macOS desktop release are separate commercial implementations rather than this repository's code.

claude-red is a library of on-demand SKILL.md files for web, identity, wireless, cloud, mobile, exploit development, red-team infrastructure, and other attack surfaces. Each skill supplies focused methodology, tooling, edge cases, and escalation paths without loading the entire library into context. It is intended for penetration testers and researchers working on systems they are explicitly authorized to assess.

Use this collection to equip coding and general-purpose agents with workflows for financial news, stock data, sentiment analysis, forecasting, signal tracking, visualization, and report generation. Individual skills can be installed with npx or copied into supported agent directories for Claude Code, Codex, OpenCode, and related tools. It is a modular skill pack rather than a standalone investment research application.

FreedomGPT is a desktop chat application for running language models on a Mac or Windows computer without sending conversations to a hosted service. The repository focuses on installing dependencies, compiling llama.cpp, and building the Electron application from source. It therefore suits users comfortable configuring and compiling a local model stack rather than expecting a turnkey client.

Antares is a cross-platform SQL client for developers who want a focused desktop workspace for multiple connections. It can edit tables, indexes, and foreign keys, manage views and stored objects, suggest queries, keep query history, open SSH tunnels, and import or export database dumps. Current support covers MySQL and MariaDB, PostgreSQL, SQLite, and Firebird SQL. The application is still under development, and some downloads are unsigned and may require extra installation steps.

Connect a single local binary to the Kubernetes API and browse topology, resources, event timelines, service traffic, Helm releases, and GitOps state without installing an agent in the cluster or creating an account. Radar keeps cluster data on the machine, includes built-in audit checks, and exposes processed cluster context through an MCP server while relying on existing Kubernetes RBAC for access control.

Siftly is a self-hosted Twitter/X bookmark manager that imports saved posts through a bookmarklet or console script and stores them in a local SQLite database. Its processing stages extract entities, analyze attached media, add semantic tags, and assign categories, enabling natural-language search, filtered browsing, an interactive mind map, and CSV, JSON, or ZIP exports. Bookmark data stays local, but content used for AI features is sent to the model provider the user configures.

Host a personal or shared library of comics, manga, and digital books, then read it through built-in web readers or OPDS-compatible clients. The server handles EPUB, PDF, CBZ/ZIP, and CBR/RAR files, with multi-user permissions, age restrictions, EPUB annotations, and Kobo or KOReader sync integrations. Docker images and prebuilt binaries offer several installation paths. The project is still explicitly considered beta before version 1.0, so users should not assume upgrades are free of breaking changes or data-loss risk.

This unofficial build wrapper converts the upstream macOS ChatGPT Desktop package into a runnable Linux Electron application. It can produce native packages for Debian, Ubuntu, Fedora, openSUSE, and Arch, along with Nix and AppImage options, while supporting both Wayland and X11. The resulting app includes the Chat, Work, and Codex interfaces, but users generally build it locally and still need a working Codex CLI for Codex features.

AingDesk is a desktop and server AI assistant that brings local models, mainstream model APIs, and local knowledge bases into one interface. Users can build agents, search the web, connect MCP services, and share configured assistants for others to use. Desktop releases are available for macOS and Windows, while the server edition can run with Docker; users still need to install local models or configure the relevant provider credentials.

ExifCleaner removes metadata from images, videos, PDFs, and many other file types through a drag-and-drop desktop interface. It can process folders recursively, show before-and-after metadata differences, preserve orientation or timestamps, and save cleaned copies instead of replacing originals. The app runs on macOS, Windows, and Linux, supports more than 90 formats, and is designed without telemetry or automatic network traffic.

CodeMachine is an orchestration layer for AI coding CLIs such as Claude Code, Codex, and Cursor. Define a workflow once and it handles step execution, context passing, and agent coordination. Workflows can range from interactive to fully autonomous, divide work among multiple agents, run tasks in parallel, and persist for hours or days. The underlying coding CLIs must be available separately.

Use an AI coding agent to review and improve web projects against Lighthouse guidance, Core Web Vitals patterns, WCAG 2.2 accessibility practices, SEO requirements, and modern browser standards. The skills work across major frameworks or plain HTML and can be invoked by topic, but this is an unofficial collection intended as structured engineering guidance rather than an official certification tool.

davidondrej-skills is a categorized library of reusable workflows for AI coding, research, and general workflow agents. Each skill lives in its own folder with a SKILL.md entry point that explains when and how it should be used. The collection covers areas such as codebase improvement, idea research, content preparation, presentation review, transcript work, skill authoring, and agent orchestration.

NVIDIA Agent Skills is an official catalog of portable guidance for NVIDIA software, installable selectively through the skills CLI for clients such as Claude Code, Codex, and Cursor. Entries are mirrored from product repositories and must include signatures, governance cards, evaluation data, and benchmark reports, giving developers a traceable way to add NVIDIA-specific workflows to their agents.
