SvelteStorm brings editing, a project tree, terminal access, browser preview, and component-state inspection into one desktop workspace for Svelte development. Its performance dashboard, split view, search, linting, and snapshot-based time-travel debugger help developers follow how interactions change application state. It targets macOS and Windows, while running the IDE from source requires the documented Node.js version and a more involved set of build prerequisites on Windows.

Revolt Desktop contains the Electron client for using and developing the Revolt chat service on a desktop. Contributors can install dependencies, build the application bundle, run it locally, and produce platform-specific packages for Linux, macOS, and Windows. The repository is useful for maintaining the existing client, testing desktop behavior, or submitting fixes. It also carries an explicit deprecation notice: a new Tauri-based desktop app is intended to replace this project, which matters for anyone considering long-term development on the current codebase.

AI Factory configures a project for selected coding agents, installs relevant skills, sets up MCP integrations, and adds spec-driven workflows for exploration, planning, implementation, fixes, review, and quality gates. It supports many agent tools, including Claude Code, Codex, and Cursor. A skills-only installation is available, but it omits the CLI, automatic MCP configuration, and interactive setup.

Use Deno to create WebView windows, communicate between frontend and backend code, and compile experimental Tauri desktop applications into executables or installers. Development requires Deno, a stable Rust toolchain, and Tauri's platform prerequisites. The repository is explicitly unmaintained, its published demo is documented as failing, and several planned capabilities remain incomplete. It is therefore better suited to studying an earlier Deno–Tauri integration approach than to serving as a dependable foundation for a new application.

Meru, formerly Gmail Desktop, puts Gmail in a dedicated cross-platform desktop window for users who do not want their inbox buried among browser tabs. The project provides downloads for macOS, Windows, and Linux and is built with Electron. Meru is a third-party client that is not affiliated with Google; Gmail remains the underlying account and mail service.

BlueBubbles Server is the macOS-side backend for the BlueBubbles ecosystem. It forwards iMessages to the Android client and sends client actions back into the iMessage environment, using local chat, message, and attachment data to provide messaging through the companion app. It is not a standalone messenger and requires both the BlueBubbles client and a working macOS iMessage environment.

The Trezor Suite monorepo maintains three related products: desktop and web applications for managing Trezor hardware wallets, a mobile application, and Trezor Connect for developers integrating wallet functionality into other software. It therefore serves both end users managing devices across interfaces and contributors building the surrounding platform. Development is primarily supported on macOS and Linux, and an emulator can be used when a physical Trezor device is unavailable.

Stringz helps Apple-platform developers localize an Xcode project without editing each resource file by hand. Open a project and it finds supported localization files, displays languages side by side, highlights missing or duplicate values, and lets you add or update strings with undo, redo, and optional autosave. It handles .strings, storyboards, XIB files, and Info.plist content for iOS, macOS, tvOS, and watchOS projects, but the editor itself runs on macOS.

Helios Launcher is designed for joining custom modded Minecraft servers without manually installing the required Java version, Forge, or server files. It supports multiple accounts, validates assets before launch, redownloads corrupt or mismatched files, switches between server configurations, displays player counts, and handles automatic updates. Installers are available for Windows, macOS, and Linux.

Windscribe Desktop is the Windows, macOS, and Linux client for the Windscribe VPN service. It supports WireGuard, OpenVPN, IKEv2, and several obfuscation protocols, along with firewall protection, per-app or network split tunneling, custom VPN configurations, and automatic connection rules. Its DNS-based blocker can filter ads, trackers, malware, and custom domains, and the client can expose an HTTP or SOCKS5 proxy to other devices on the network.

Factory is a software-development platform built around the Droid coding agent, with workflows available through the CLI, web, Slack or Teams, Linear or Jira, and mobile. Its ecosystem includes a VS Code extension, ACP integration for JetBrains and Zed, TypeScript and Python SDKs, and a GitHub Action for pull-request reviews, security scans, and descriptions. The CLI can be installed on macOS, Linux, and Windows.

Pipedash combines pipelines from GitHub Actions, GitLab CI, Bitbucket, Buildkite, Jenkins, Tekton, and ArgoCD in one interface. Teams can inspect status and run history, trigger workflows with provider-specific parameters, repeat earlier runs, or cancel active builds. It is available as a desktop app for macOS, Windows, and Linux, an iOS app, or a self-hosted Docker web deployment. Credentials can use the system keyring or encrypted SQLite or PostgreSQL storage; remote web deployments should set the vault password so the API is not left open.

Task Observer is a meta-skill that runs alongside normal work, capturing corrections, judgment calls, and repeated workflow gaps. It turns those observations into proposed updates for existing skills or drafts for new ones, so a skill library can evolve from actual use rather than remain frozen. The fullest experience is available in Claude environments with filesystem access, where logs and proposals persist between sessions; web and mobile use a handoff-document mode instead.

Loki Mode turns a PRD, issue, API specification, or short brief into a repository with source, tests, configuration, and audit records. Its agents repeat reason-act-reflect-verify cycles, while deterministic gates block empty diffs, failing tests, and inconclusive checks from being reported as complete. Each run can produce evidence that the completion claim can be rechecked.

The pack lets Claude Code or Cursor drive the Arcads API to create short videos, static Meta ads, thumbnails, and multi-step animated campaigns using model-specific prompt libraries. Basic image and video workflows require Python 3.10+ and an Arcads API key, while captioning, stitching, or publishing pipelines may also need ffmpeg, Node.js, or other CLI tools.

Android Messages Desktop wraps the Android Messages web experience in a standalone application for Windows, macOS, and Linux, avoiding the need to keep a browser tab open. It adds system notifications, macOS badges and menu-bar behavior, Windows and Linux tray support, background operation, and multilingual spell checking. The project is not affiliated with Google, and its Windows binary is unsigned; signing Windows releases remains an unfinished roadmap item.

guard-skills supplies focused second-pass reviews for production code, tests, documentation, WordPress, and WooCommerce work. Run the relevant guard after an agent changes a repository to catch patterns such as needless abstraction, ineffective tests, documentation drift, or platform-specific mistakes before commit or merge. The package is primarily Markdown and includes no executable scripts, network calls, or credential requirements.

Lichtblick gives robotics developers an integrated interface for visualizing data and diagnosing system behavior. It runs directly in a browser without installation, or as a desktop application on Linux, Windows, and macOS, and it can also be self-hosted with Docker. Building from source requires Node.js. Linux users choosing the .tar.gz package may need to install missing desktop libraries manually.
