Hush is a Safari content blocker for iOS and macOS that removes many cookie-consent and privacy-tracking overlays. After installing it, enable the blocker in Safari settings; its rules run locally without access to browsing habits, passwords, or crash reports. It does not click consent buttons, decide cookie permissions, or block ads. Some sites may still show notices when hiding them would break the page or when the site actively resists blocking.

Browserbase Skills adds installable browser workflows to Claude Code through the official browse CLI. An agent can automate local or remote browsing, test websites, capture detailed browser traces, infer APIs from observed traffic, or deploy browser automation as cloud functions. It can start an isolated local browser or reuse an existing Chrome session when cookies and sign-in state are needed.

This unofficial desktop client brings Google Assistant to Windows, macOS, and Linux through the Google Assistant SDK, with release installers and common package-manager options. Before it can work, users must complete device registration and authentication to obtain a key file and token. The application remains under development and is not an official Google client.

Acontext is an open-source memory layer that captures reusable lessons from AI-agent runs and stores them as ordinary Markdown Skill files. Developers can read, edit, version, mount, or share those memories across models and frameworks without relying on embeddings or a closed memory format; agents retrieve the needed files through tools and reasoning. Users can connect to the hosted service with an API key or self-host the backend with Docker, which requires an OpenAI API key.

Go Music DL brings multi-platform song, playlist, and album search into one interface, with playback, downloads, batch actions, source replacement, and local library management. It can run as a web app, terminal interface, desktop app, or mobile build. Some personal playlists and higher-quality sources require platform cookies, while metadata embedding and related enhancements may depend on FFmpeg.

cc-sdd installs a spec-driven development workflow as Agent Skills, moving from discovery, requirements, and design into task generation and long-running implementation. Each task can be handled by a fresh implementer using test-driven development, followed by an independent reviewer and an automatic debugging pass. The same seventeen skills target eight coding agents and thirteen languages; Claude Code and Codex are stable, while the other integrations remain beta.

Pagedraw is a visual UI builder for React that works more like Sketch or Figma than a conventional code editor. It stores the design in a Pagedraw document, generates JSX and CSS into the project, and updates a local React app as you edit. The generated files remain regular source code if you later remove Pagedraw. Development has stopped and the maintainers explicitly advise against production use, so it is mainly useful for experimentation, study, or a fork.

AgentBench measures how well LLMs act autonomously across eight interactive environments, including database and operating-system tasks. The current repository carries a function-calling version integrated with AgentRL, while the older benchmark remains available as v0.1. Running the suite requires Docker, and Python 3.9 is recommended because several scientific dependencies are pinned to older versions.

Organize remote hosts, restore sessions, split terminals, and transfer or edit files through a dual-pane SFTP browser on macOS, Windows, or Linux. The built-in Catty Agent can run diagnostics and coordinate multi-host operations from natural-language requests. Netcatty connects to remote or local shells through SSH and related protocols; it is not a shell replacement.

Codex++ patches the locally installed Codex Desktop app so a small runtime can load tweaks from a user-owned folder. Those tweaks may alter the interface, add settings pages, run main-process code, or use OS-level features through its native bridge, while runtime files, configuration, logs, backups, and tweak data remain outside the app bundle. A watcher can reapply the patch after Codex updates. This is an unofficial modification that executes local extension code, so users should rely on its diagnostics, safe mode, repair, and uninstall controls.

tradingview-mcp exposes market quotes, screeners, technical indicators, sentiment, and strategy backtests for stocks, crypto, forex, and futures through MCP. It can be self-hosted for free or used through a managed connector. The server does not sign in to TradingView or place trades, and it is an independent project using third-party data that may be delayed or incomplete; its outputs are informational rather than financial advice.

LBRY Desktop bundles the protocol daemon with a graphical browser and wallet for the LBRY decentralized content marketplace. Installers are provided for Windows, macOS, and Debian-based Linux, and the installed application connects to the LBRY network for browsing content and using the accompanying wallet.

BilibiliVideoDownload is a desktop downloader for Windows, macOS, and Linux that handles regular videos, series, multipart content, and movies that do not require an extra purchase. It can also save covers, subtitles, and danmaku. Available resolution depends on authentication: up to 480p without login, 1080p for a standard account, and up to 8K for eligible premium accounts. Paid and region-restricted videos are unsupported, and bundled FFmpeg makes the installer relatively large.

Command Code builds features, fixes bugs, writes tests, and refactors inside an interactive terminal session. Its Taste system treats accepted, rejected, and edited output as signals, gradually adapting to how you prefer code to be written. Taste profiles can also be pushed and pulled for use across a team.

Tad is a desktop application for opening and analyzing CSV, Parquet, SQLite, and DuckDB data sets. Its hierarchical pivot table supports filtering, aggregation, sorting, column selection, ordering, and basic formatting, while DuckDB generates the analytical queries behind the interface. It can be launched with a file path from the command line and uses SlickGrid to keep scrolling responsive on very large files.

mhrv-rs runs a local HTTP and SOCKS5 proxy that forwards requests through a Google Apps Script deployed under your own account, concealing the destination from the ISP at the TLS SNI layer. Setup requires creating the relay, choosing an auth secret, installing a local certificate, and configuring the browser or system proxy. Google can still see destination sites, and Apps Script quotas or unsupported video CDNs can limit usage.

Devon is an open-source pair-programming agent available through a web interface or terminal UI. It can explore a repository, edit multiple files, write tests, fix bugs, and accept corrections while it works. Installation requires Node.js, pipx, and at least one Anthropic, OpenAI, or Groq API key; support for non-Python projects is limited, while Windows and local-model modes remain immature.

Platypus is a macOS developer tool that wraps shell, Python, Ruby, JavaScript, PHP, and other command-line scripts in native application bundles. The generated apps can show progress or output, accept dropped files, send notifications, run as status items, or work in the background. A graphical interface and command-line tool support both interactive packaging and automated builds.
