Duckling is a lightweight desktop viewer for quickly browsing CSV and Parquet files, DuckDB databases, folders of data, and SQLite. It also offers experimental connections to PostgreSQL, MySQL, ClickHouse, and Doris or StarRocks. The project deliberately focuses on fast inspection rather than full database administration. It is actively developed, currently unstable, and its experimental database integrations have received limited testing.

Voicetypr turns a global hotkey into voice input for the application currently in focus on macOS or Windows. By default, recordings are transcribed locally with a downloaded model, while cloud speech services are used only when the user selects one; telemetry is opt-in and disabled by default. Initial setup requires microphone access, a model download, and accessibility permission on macOS. It is suited to people who frequently write, code, or compose long prompts by voice.

Skald packages document ingestion, chunking, embeddings, vector storage, retrieval, and cited chat behind a configurable API. Teams can tune search, reranking, models, and query rewriting, then evaluate the resulting RAG setup through the same platform and access it from several language SDKs. It can run as a hosted service or through Docker in your own environment; a fully local deployment also requires self-hosted LLM inference and embeddings.

Install MyKVM on Windows, macOS, or Linux machines, choose one computer as the server and another as the client, then arrange their screens to match your desk. Moving the pointer across a shared edge transfers keyboard and mouse control, while text and image clipboards synchronize in both directions. Devices can discover each other on the same LAN or connect by IP. The current release is an experimental trusted-network prototype without pairing codes or authenticated discovery, so its transport ports should never be exposed to public or untrusted networks.

Semia analyzes an Agent Skill before the user decides to trust or run it. The scanner reads the skill as data and never executes its embedded commands, then identifies possible actions, effects, network access, secret reads, and tool invocations with evidence tied to source lines. It can be used through a Python CLI or installed as a plugin for Codex, Claude Code, or OpenClaw. A configured LLM provider is required for the full prepare, synthesize, detect, and report workflow.

OmniSearch is a Windows desktop app that reads NTFS MFT and USN metadata for fast global search, advanced filtering, duplicate detection, and common file actions. After the initial scan, a journal watcher keeps the index updated incrementally. An optional Android companion pairs by QR code over the local network for browsing and transferring files. The desktop engine requires Windows 10 or 11, an NTFS volume, and elevated access to read volume metadata.

Authme is a cross-platform authenticator for managing time-based two-factor codes on the desktop or web. Add accounts from TOTP QR codes or import existing data from Google Authenticator, 2FAS, or Aegis, then protect the stored codes with password-based AES-256 encryption. It works offline apart from update checks and includes export and backup options for users who want to retain control of their authenticator data.

langgraph-bigtool stores tool names, descriptions, namespaces, and other metadata in a LangGraph Store so an agent can search for relevant tools before calling them. It is designed for registries containing hundreds or thousands of tools, supports in-memory and PostgreSQL backends, and lets developers replace the default retrieval logic with a custom function.

Rockxy is a native macOS debugging proxy for capturing HTTP and HTTPS traffic, inspecting APIs and protocols such as WebSocket or GraphQL, and reproducing issues with response mocking or rewriting. A local redaction-aware MCP server can expose selected captures to assistants such as Claude Desktop or Cursor for troubleshooting. The current quick start builds the application from source with Xcode 16 on macOS 14 or later, and initial setup includes installing a helper and trusting a local root certificate.

OpenDirectory packages dozens of agent skills for founders working on go-to-market, growth automation, technical marketing, and related developer tasks. Its terminal browser lets you search by category and install individual skills into runtimes such as Claude Code, Codex, Gemini CLI, OpenClaw, or Hermes. The recommended interactive installer runs through npx and therefore requires Node.js.

affiliate-skills organizes affiliate marketing into reusable workflows for program research, trend scouting, evidence-backed briefs, content and infographic creation, landing pages, deployment, analytics, compliance, and campaign improvement. Users can invoke one task or chain stages into a broader flywheel. Exact live engagement and traffic metrics depend on optional external data integrations.

Android TV Toolkit is a Windows application for managing compatible Android TV devices over wireless ADB. It can remove known bloatware and Google TV recommendations, install APKs, reboot the device, and disable the stock launcher after a replacement such as FLauncher is installed. Safe and advanced debloat modes separate lower-risk choices from cautionary or critical packages. The current version requires Python 3.8+, PySimpleGUI, and a TV with ADB debugging on the same network, and the project is not actively maintained.

Spring AI Agent Utils gives Java developers a reusable toolkit for building coding assistants and multi-agent workflows with Spring AI, covering file and shell access, code and web tools, task state, memory, and extensible skills. It is distributed as Maven modules with examples, requires Java 17 or newer, and includes an A2A module for delegating to remote subagents.

SJMCL manages multiple Minecraft directories and instances on Windows, macOS, and Linux, including saves, mods, resource packs, shaders, screenshots, and settings. It can download game clients, loaders, and packs from CurseForge or Modrinth, and supports Microsoft accounts plus compatible third-party authentication servers. Extensions, deep links, and MCP services add automation options; the launcher is not an official Mojang or Microsoft product.

bggg-skills is a collection of independently installable Codex Skills for creative and operational work. It includes workflows for converting images into layered PSD files, rebuilding designs as editable PPTX decks, improving other skills, researching and processing TikTok content, and analyzing or tracking Amazon Sif keywords. Users copy or symlink only the skill directories they need into their Codex skills folder. Some workflows require additional Python packages listed within their own directories.

Compose Agent Skill equips coding assistants with 24 practical guides and six source snapshots from AndroidX and Compose Multiplatform projects. Its routing workflow directs the agent to relevant material for state, modifiers, performance, navigation, side effects, and platform-specific behavior, helping it verify APIs instead of guessing. The plugin can be installed into supported hosts including Claude Code, Codex, Copilot, Cursor, and Gemini CLI.

RepoMaster turns a natural-language task into a workflow that discovers suitable GitHub repositories, understands how to use them, and coordinates specialized agents to execute the work. It offers web and command-line modes for deep search, general assistance, or repository-focused tasks. A model key is required, while deep search also needs Serper and Jina credentials.

Saga Reader is a desktop reading application that gathers online information from user-defined interests through search and RSS. It can pass collected articles to a local or cloud LLM for summarization, translation, guidance, and an interactive reading conversation. Interest prompts, source articles, and processed content are stored on the user's computer rather than in a hosted account. Retrieval still depends on available search providers, while AI processing depends on the model backend the user configures.
