Packages

Distributed, reliable key-value store for the most critical data of distributed systems. etcd uses the Raft consensus algorithm to maintain a strongly-consistent, highly-available store. Kubernetes uses etcd as its primary datastore. Agent systems use etcd for distributed coordination: leader election, service discovery, distributed locks, and configuration management.

MCP server that converts Figma designs to pixel-perfect HTML/CSS code, supporting React, CSS Modules, and Tailwind CSS output with automatic image asset localization.

MCP server enabling AI assistants to interact with iOS simulators on macOS. Provides 13 tools for UI interaction (tap, swipe, type), screen capture (screenshot, video), app management (install, launch), and accessibility inspection.

MCP server enabling AI models to interact with Notion workspaces — retrieve, create, update, and delete blocks, pages, databases, comments, and users. Supports experimental Markdown conversion to reduce token usage.

Python library for creating and modifying Microsoft Word .docx files — generates structured Word documents programmatically. python-docx features: Document class (new or existing), add_paragraph() and add_heading(), add_run() for inline text with formatting (bold, italic, font size, color), add_table() with cell access, add_picture() for inline images, styles (Heading 1, Normal, Quote), paragraph formatting (alignment, indentation, spacing), section page setup (landscape, margins), add_page_break(), list styles (bulleted, numbered), hyperlinks via XML, and core properties (author, title). Standard library for generating Word document reports from agent data.

Manages inbound webhooks from third-party services with reliable queuing, filtering, transformation, fan-out routing, and automatic retry on delivery failures.

The 'modern monolith' approach to building single-page apps. Inertia.js replaces the traditional SPA API layer — instead of building a JSON API for your React/Vue/Svelte frontend, Inertia renders page components directly from your server routes (Rails, Laravel, Django) and handles client-side navigation without page reloads. You get SPA-like UX without building a separate API. Often called 'the missing piece between server-side and SPA'.

Microsoft Power BI REST API for programmatic access to Power BI workspaces, datasets, reports, and dashboards. Enables AI agents to query data models, refresh datasets, embed reports, manage workspaces, and retrieve analytics data — integrating enterprise BI assets into agentic workflows.

Agentic framework that automatically generates complete PowerPoint presentations from documents, research topics, or freeform prompts, with reflective design capabilities and text-to-image asset generation.

Bridges AI models (Claude, GPT, Gemini) with ROS/ROS2 robots via MCP, enabling natural language command translation into ROS commands and real-time robot state monitoring without modifying existing robot source code.

PostgreSQL-backed tool that transforms compressed Reddit/Voat/Ruqqus data dumps into searchable HTML archives with full-text search, REST API, and an MCP server with 29 tools for AI assistant integration.

MCP server for Reddit Advertising API enabling AI agents to manage Reddit ad campaigns end-to-end — across accounts, funding methods, campaigns, ad groups, and creatives. Enables programmatic Reddit advertising management from AI agents.

Provides fast, low-cost access to Google Search results as structured JSON via a simple REST API, covering web, news, images, and shopping searches.

Provides state-of-the-art embedding models and rerankers optimized for retrieval accuracy, used by Anthropic and trusted for RAG pipelines.

Async HTTP client (and server) for Python using asyncio. aiohttp's ClientSession makes async HTTP requests with connection pooling, streaming, WebSocket support, and cookie management. The standard for async HTTP in Python before httpx's rise. Still widely used for WebSocket connections (aiohttp supports WS natively), streaming downloads, and legacy async codebases.

Distributed task queue for Python — sends tasks to workers asynchronously via message brokers (Redis, RabbitMQ). celery 5.x features: @app.task decorator for task definition, .delay()/.apply_async() for dispatching, task.AsyncResult for result retrieval, periodic tasks via celery beat, task chaining/grouping/chord with canvas API, retry logic, task routing to specific queues, priority queues, result backends (Redis, database), task monitoring via Flower, soft/hard time limits, task ETA (eta= parameter), countdown=, rate_limit=, workflow primitives (chain, group, chord), and task signals.

Microsoft's open-source C/C++ library manager with 2,000+ ports (packages). vcpkg integrates natively with CMake and MSBuild, supports manifest mode (vcpkg.json for project-specific dependencies), and provides binary caching for CI. Originally Windows-focused but now fully cross-platform (Linux, macOS, Windows). Provides CMake toolchain integration that automatically makes installed packages available to CMake's find_package().

Apaleo open cloud hotel platform REST API for innovative hotel operators, tech-forward hotel groups, and hospitality technology developers to build custom hotel management experiences on a headless, API-first property management system. Enables AI agents to manage property and unit type configuration for hotel product catalog automation, handle reservation lifecycle management for hotel booking automation, access rate and availability management for hotel revenue optimization automation, retrieve financial account and folio management for hotel billing automation, manage housekeeping assignment and room status for hotel operations automation, handle payment processing and tokenization for hotel transaction automation, access guest communication integration via Apaleo App Suite for hotel guest engagement automation, retrieve reporting and analytics data for hotel business intelligence automation, manage multi-property configuration for hotel group management, and integrate Apaleo with the Apaleo App Store ecosystem (200+ apps) for end-to-end custom hotel technology stack building.

Elixir library for running pre-trained HuggingFace neural network models — BERT, GPT-2, Whisper, CLIP, Stable Diffusion, and more — directly in Elixir without Python. Built on Nx (tensor operations) and Axon (neural network layers). Bumblebee downloads model weights from HuggingFace Hub and runs inference via EXLA (XLA GPU backend) or BinaryBackend (CPU). Enables LLM inference, text classification, NER, speech recognition, image classification, and text embedding in pure Elixir. Integrated with Livebook Smart Cells for notebook exploration.

Cloudflare's Zero Trust API provides programmatic control over Cloudflare Access (application authentication), Cloudflare Gateway (DNS/HTTP/network filtering), Cloudflare Tunnel (secure connectivity), and WARP (device enrollment) — enabling automated SASE/ZTNA policy management.
