Manta is a desktop invoicing app for freelancers and people who occasionally need invoices, estimates, or receipts without adopting a full accounting service. Users can enable or hide form fields, reorder line items by dragging, customize templates and statuses, and export a PDF for printing or email. Financial data stays on the local machine, but the project describes itself as beta software rather than a complete bookkeeping system.

Altair GraphQL Client is a cross-platform GraphQL client IDE for debugging queries and GraphQL implementations. It is available through desktop applications and browser extensions, giving developers a dedicated interface for investigating query-related issues. Its role is client-side development and debugging, not running a GraphQL server.

MineContext is a desktop assistant that builds a record of a user's digital workflow from sources such as screen captures and uploaded links, then uses that context to surface proactive insights. The project describes its data processing and storage as local-first, which suits people who want an AI companion to understand ongoing work, study, or creative activity. On first launch it installs a backend environment and requires a Doubao, OpenAI, or OpenAI-compatible local or third-party model service.

ProxyBridge redirects traffic from proxy-unaware applications through HTTP or SOCKS5 proxies on Windows, macOS, and Linux, with per-process rules for proxying, direct connections, or blocking. Its GUI and CLI suit security testing, protocol analysis, and selective routing. The implementation uses platform-level interception, so supported OS versions, kernel features, and elevated permissions vary by system.

Clawd on Desk turns agent activity into an animated pixel pet that reacts to thinking, typing, permission requests, subagent work, and completion. A session dashboard helps track several tasks at once, while Claude Code and Codex connect automatically and other agents can be configured manually. It runs on Windows, macOS, and Linux, with an optional read-only phone view over the local network.

Pomotroid runs customizable work and break cycles and records completed sessions across daily, weekly, and all-time views, including charts and a 52-week heatmap. It also offers global shortcuts, tray controls, notifications, custom themes, and an optional local WebSocket server for overlays or automation. Current builds are unsigned, so the operating system may warn on first launch.

Gitify is a menu-bar or system-tray application for macOS, Windows, and Linux that consolidates notifications from GitHub Cloud, GitHub Enterprise, Gitea, Forgejo, and Codeberg. Users can configure filters, themes, and notification behavior, while actions such as mark read, mark done, unsubscribe, and enriched details vary by forge. GitLab, Bitbucket, Azure DevOps, and Gerrit are future considerations rather than supported integrations.

AYA provides a graphical desktop interface for common Android Debug Bridge workflows. After connecting a device, developers can mirror its screen, browse files, manage applications, inspect layouts, view Logcat, open a shell, and monitor processes or performance. Release packages are available for Windows, Intel and Apple Silicon Macs, and x86-64 Linux, making it useful for teams that prefer visual device management over repeated ADB commands.

Simplenote for Electron is the official Simplenote desktop client for Windows and Linux, using React for the interface, Electron for packaging, and Simperium for synchronization. Regular users can install the released application, but local development currently requires an existing test-server account or access to production credentials, and development builds do not support sharing or publishing API features. The repository also includes testing and packaging workflows.

Flying Carpet sends files between Android, iOS, Linux, macOS, and Windows devices over ad hoc Wi-Fi, without a router, cellular connection, or preconfigured network share. It is useful for moving large files between different platforms when only nearby Wi-Fi-capable devices are available. Apple devices cannot use it for Apple-to-Apple transfers, and some transfer modes temporarily interrupt the existing wireless internet connection.

AstronRPA provides a low-code and no-code desktop designer for automating Windows applications, browsers, office files, data processing, image recognition, and system operations through prebuilt workflow components. Processes can run directly, on schedules, through APIs or MCP, and can exchange capabilities with the separate Astron Agent platform. It primarily targets Windows 10 and 11 and is designed for team or enterprise deployments that normally include a Docker-based server and a configured desktop client.

TagSpaces is an offline desktop application for browsing, tagging, searching, and managing local files on Windows, Linux, and macOS. Tags can live in filenames or sidecar metadata, while built-in tools handle notes, task lists, and common audio or video playback. Its browser extension saves web pages or screenshots locally, so the core workflow does not depend on a cloud service or internet connection.

LyricsX searches multiple lyric sources and displays live lyrics on the macOS desktop or menu bar while supported music players run. Users can adjust typography and timing, double-click a line to seek, import or export lyric files, and convert Traditional and Simplified Chinese. Its LRCX format supports word timing and translations, but the project notes that no official LRCX editor is currently available.

PureMac scans macOS caches, developer-tool data, and files left behind by uninstalled apps, with a native interface for cleaning and app removal. Items are moved to the Trash rather than permanently deleted, and the app reports no telemetry. Full Disk Access is needed to inspect protected locations and remove related files from app containers.

TablePro is a native database client with built-in drivers for MySQL, PostgreSQL, SQLite, Redis, and several related engines, plus installable plugins for databases such as MongoDB, SQL Server, and Oracle. It combines a SQL editor, editable data grid, SSH tunnels, query history, AI assistance using a chosen provider or Ollama, and an MCP server. Stable releases currently target macOS 14+ and iOS or iPadOS 18+, while Linux support remains in development.

ONLYOFFICE Desktop Editors is an open-source desktop suite for Windows, Linux, and macOS that works with documents, spreadsheets, presentations, PDFs, PDF forms, and diagrams without an internet connection. It supports Office Open XML files and can connect to cloud services for collaboration, while also offering signatures, password protection, plugins, and AI assistants. The project is licensed under GNU AGPLv3.

Papra is a minimal self-hosted platform for long-term storage and management of receipts, warranties, and other personal or organizational documents. Full-text search, filters, tags, and custom properties help retrieve files, while email and folder ingestion can import them automatically and extract text from images or scans. Documents may be shared externally with expiration dates and password protection. A Docker image provides a quick deployment path, but real installations should use a securely generated authentication secret.

MQTTX presents MQTT testing in a chat-like interface where several client connections can stay online at the same time. It helps verify connection, publish, and subscribe behavior over MQTT/TCP, MQTT/TLS, and MQTT/WebSocket while formatting message payloads for inspection. The desktop client runs on Windows, macOS, and Linux and can connect to EMQX or other brokers.
