Tonkatsu Box is a cross-platform personal collection manager for games, movies, television, anime, manga, visual novels, books, and comics. Users can search external catalogs, import existing libraries, track status and ratings, build visual boards or tier lists, and continue using the app offline after setup. Local-network device sync copies the entire database and replaces the receiving device instead of merging changes, while macOS and Linux support is currently described as experimental.

Notepanda is a deliberately simple cross-platform text editor with basic editing, line numbers, syntax highlighting, and a preview panel for Markdown and HTML. Files can be opened by drag and drop or passed directly when launching the app from a shell. Releases are available for Windows, macOS, and Linux, but the author presents it as a small learning project rather than a full replacement for mature professional editors.

Claude Code Trace turns session files from the local Claude projects directory into readable conversations. It supports searching by user message, expanding tool and MCP calls, inspecting timestamps and token counts, and following active sessions in real time. The viewer is available as a desktop app, web interface, or terminal UI and does not require sending traces to an external service.

Lovcode gives developers a desktop workbench for launching Claude Code, Codex, terminal, and other AI coding sessions from a selected project. It indexes local histories and exposes tool calls, linked files, generated images, and usage details, making previous work easier to find and resume. Users can copy handoff context between agents and manage commands, MCP servers, skills, hooks, runtimes, and model providers from one interface. Desktop releases target macOS, Windows, and Linux.

TermCanvas places terminals on a zoomable spatial canvas organized by project, Git worktree, and session, making parallel coding agents easier to monitor. You can see agent state, reopen conversations, inspect diffs and repository status in place, and use the bundled CLI or Hydra toolkit to launch isolated workers. It runs as a desktop app on macOS, Windows, and Linux; the described cloud runtime is still a roadmap item.

PaintFE is a local raster image editor for drawing, retouching, and working with layered documents, RAW photos, GIFs, and APNG animations. Repetitive edits can be scripted in the built-in Rhai editor or run from the command line across batches of files. Releases are readily available for Windows and Linux; macOS builds are unsigned and require a manual first-launch approval.

Markdown Viewer pairs a GitHub-style editor with a synchronized live preview for code, math, Mermaid and other diagrams, and richer technical content. It supports multiple document tabs plus PDF, HTML, and PNG exports, and can run as a hosted web app, a desktop application, or a Docker deployment. Normal editing, autosave, local file access, and most exports stay on the device without an account, while remote imports, sharing, and selected renderers use the network only when invoked.

ClawSuite is a self-hosted command center for OpenClaw agents, delivered primarily as a web application and installable PWA. It combines multi-agent mission control, live output streaming, chat, cost analytics, task boards, cron management, memory and file browsers, terminal access, and gateway diagnostics. It suits users who need a central operational view of agent activity, while the native desktop application and managed cloud edition are still described as works in progress.

OpenTypeless provides voice-first workflows across macOS, Windows, and Linux. A global shortcut can transcribe speech, optionally polish it for the active application, and insert or copy the result; separate flows rewrite selected text, translate content, or return a one-shot answer in a small floating note. Users can choose among multiple speech and language-model providers and customize shortcuts, dictionaries, and per-app behavior.

Repo Wizard keeps developers in control when applying code changes suggested by an LLM. Users open a local project, select the files that should become context, generate a prompt, and paste the model's response back into the app. The proposed edits are organized into review sessions with side-by-side diffs, so every change can be inspected before it is applied. It is model-agnostic, but the project is developed mainly on macOS and may be less stable on Windows or Linux.

Usage4Claude displays Claude and Codex quota usage, reset countdowns, and extra credits directly in the macOS menu bar. It supports several limit types, multiple accounts or organizations, configurable indicators, and notifications when usage approaches a threshold or resets. Authentication is completed through the built-in browser or session credentials and must be renewed after expiration; the released app currently targets macOS.

Harnessclaw is an Electron desktop application for configuring AI agents, chatting with them, browsing skills through ClawHub, and reviewing session history from a single interface. It is aimed at users who want a visual control surface instead of managing each agent workflow separately. The current documentation focuses on installing dependencies and building from source with Node.js and Yarn, with build targets for macOS and Windows.

Nomi is a local-first desktop workspace for taking an AI video from an idea to an exported MP4. It connects script writing, shot planning, image and video generation, reusable assets, and timeline editing in one project. A 3D staging area lets creators position characters and cameras, lock character identity, and define camera paths so visual intent can be passed to generation models more precisely. Users bring their own model endpoint and API key, with desktop builds for macOS and Windows; generation quality, availability, and cost depend on the connected services.

FaceGate adds per-application locking to macOS and can authenticate with local face recognition, Touch ID, or a password. It supports liveness challenges, multiple enrolled faces, external cameras, and configurable unlock sessions for individual apps, with recognition and credential handling kept on the Mac. The app is not Apple-notarized, so manual installation requires removing its Gatekeeper quarantine attribute.

SONE gives Linux users a native desktop client for browsing their TIDAL library, managing playback, and sending lossless audio directly to an ALSA device or DAC at source rates up to 24-bit/192kHz. It also includes synced lyrics, a floating mini player, and scrobbling integrations. An active TIDAL subscription is required, and the client streams music only rather than supporting offline downloads.

Gemini Desktop places Google Gemini in a dedicated app with multiple conversation tabs, a global-hotkey Quick Chat window, tray controls, always-on-top mode, and response notifications. Releases are available for Windows, macOS, and Linux, with no application telemetry; authentication remains handled by Google. Development has been on hiatus since July 2026, so existing builds remain available but new fixes are not planned and issues or pull requests may go unanswered.

YouTube Comment Suite is a cross-platform JavaFX desktop application that aggregates comments from multiple YouTube videos, playlists, and channels for archiving, search, and activity analysis. It filters by video, type, username, keyword, length, or date, summarizes publishing and commenter activity, and saves thumbnails and user profiles for offline reference. Release packages expect Java 8; Java 11 and later require the workaround documented in the project wiki.

Porda AI is an on-device Windows application for users who want to maintain Islamic modesty while browsing or watching media. It detects and covers non-mahram people and NSFW objects directly on screen across browsers, video players, and other applications, with hotkeys and per-app controls. Processing stays offline, but very small objects may be missed, performance depends on the computer, and GPU acceleration is currently limited mainly to Intel OpenCL hardware.
