Packages

Tiny, elegant HTTP client built on the Fetch API for browsers and Node.js 18+. Ky adds retry logic, timeout, JSON convenience methods, hooks (beforeRequest, afterResponse), error handling for 4xx/5xx, and status-based error throwing on top of native fetch — all in ~2KB. The modern, fetch-native alternative to axios for applications targeting modern browsers and Node.js 18+.

Community-driven open-source fork of Terraform under CNCF. OpenTofu maintains compatibility with Terraform HCL configurations while remaining truly open-source (MPL-2.0). Provides the same CLI workflow (init, plan, apply), provider ecosystem compatibility, and state management as Terraform. Added features: native state encryption, provider functions. Drop-in replacement for Terraform when HashiCorp's BSL license is a concern.

Community MCP server for Oura Ring health wearable. Connects to Oura Ring cloud API to enable AI agents to access wellness data — sleep scores, HRV, readiness, activity, and biometric trends. Enables AI health assistants and personal analytics agents to incorporate Oura biometric data into wellness coaching and analysis workflows.

Python dependency management and packaging tool using pyproject.toml that handles dependency resolution, lock files, virtualenv management, and PyPI publishing in a single workflow.

HTTP mocking library for Python's httpx client. RESPX intercepts httpx requests in tests and returns mocked responses without making real network calls. The async-native equivalent of responses (for requests) but designed for httpx. Essential for testing agent code that makes HTTP calls without hitting real APIs.

The de facto JVM logging standard: SLF4J (Simple Logging Facade for Java) provides a vendor-neutral logging API; Logback is the native implementation (successor to Log4j). SLF4J's Logger interface lets library code log without binding to a specific implementation — the application chooses the backend (Logback, Log4j2, java.util.logging). Logback provides file rolling, JSON formatting, async appenders, and conditional logging.

High-performance Python web scraping and crawling framework. Scrapy provides a complete spider lifecycle (request scheduling, downloading, parsing, pipeline processing) with async I/O via Twisted. Built-in support for robots.txt, rate limiting, cookie handling, caching, and item pipelines for storing scraped data. The de-facto standard for large-scale Python web scraping.

HTTP assertion library for Node.js that enables testing Express, Koa, Fastify, and other Node.js HTTP servers without starting a real server. SuperTest wraps superagent (HTTP client) with test assertion capabilities — make HTTP requests to your server in tests and assert on response status, headers, and body in a fluent API. The standard choice for Node.js API integration testing with Jest or Mocha.

Fully type-safe React router with first-class search parameter support. TanStack Router generates TypeScript types for all routes, parameters, and search params, making route navigation fully type-checked — typos in route names are compile errors. Supports file-based routing (like Next.js) and programmatic route definitions. Key differentiator: search parameters are treated as first-class state (typed, validated, serialized) rather than strings.

Lightning-fast ASGI server for Python, built on uvloop and httptools. The standard server for running FastAPI and Starlette applications. Supports HTTP/1.1, HTTP/2, WebSockets, and Server-Sent Events. Used in development (uvicorn app:app --reload) and production (with Gunicorn as process manager).

Decorator-based validation for TypeScript/JavaScript classes. Add validation decorators (@IsString(), @IsEmail(), @MinLength(5)) to class properties and call validate(instance) to check validity. Works with NestJS DTOs (Data Transfer Objects) as the standard validation approach. Built on validator.js for the underlying validators. Part of the typestack ecosystem alongside class-transformer.

A light-weight module that brings the browser's Fetch API to Node.js. Implements the WHATWG Fetch specification so browser-written fetch() code runs unchanged in Node.js. Note: Node.js 18+ includes native global fetch() — node-fetch is primarily useful for Node.js 16 and below, or when you need the exact WHATWG Fetch behavior with additional options. v3 is ESM-only; v2 supports CommonJS.

Human-friendly Python job scheduler. Provides a simple fluent API for scheduling Python functions: `schedule.every(10).minutes.do(job)`. Jobs run in the same process via polling loop. Extremely simple alternative to APScheduler or Celery Beat for basic periodic task execution without external dependencies. No daemon process, no persistence, no distributed execution.

Full-featured web crawling and scraping framework for Python — provides Spider classes, async Twisted reactor, item pipelines, middleware, and built-in request scheduling. scrapy features: Spider subclasses with parse() callback, Selector for CSS/XPath extraction, Item and ItemLoader for data modeling, pipeline for processing (deduplication, validation, DB storage), downloader middleware (rotating proxies, user agents), CrawlerProcess for programmatic control, crawl rules for link following (CrawlSpider), sitemap crawling, feed exporters (JSON, CSV, XML), AutoThrottle, robots.txt compliance, and scrapy-splash for JS rendering.

Open-source static analysis security scanner for Terraform IaC. Detects security misconfigurations in Terraform configurations before deployment — checks for insecure S3 buckets, open security groups, unencrypted resources, missing logging, and hundreds of other cloud security best practice violations across AWS, Azure, GCP, and other providers. Part of Aqua Security's open-source toolchain.

Modern, accessible drag and drop toolkit for React. Modular architecture with sensors (mouse, touch, keyboard), collision detection algorithms, and composable modifiers. @dnd-kit/sortable builds sortable lists and grids. Designed for accessibility (keyboard DnD, screen reader announcements). Replacement for react-beautiful-dnd (deprecated) and react-dnd.

The industry-standard enterprise-grade data grid for JavaScript. AG Grid handles millions of rows with row virtualization, supports React/Angular/Vue/vanilla JS, and provides 100+ features: sorting, filtering, grouping, pivoting, tree data, row editing, clipboard, Excel export, charts, and server-side row model for large datasets. Used by major financial institutions, Bloomberg, and large enterprise applications where a simple HTML table or Tanstack Table isn't sufficient.

AccuWeather REST API for enterprise-grade weather data, forecasts, severe weather alerts, and weather intelligence products. Enables AI agents to manage real-time weather conditions and minute-by-minute forecasts for precision weather-triggered automation, handle severe weather alerts and warning retrieval for weather risk management, access extended 45-day daily and 90-day monthly forecasts for long-range planning automation, retrieve historical weather data and climate trends for weather analytics, manage air quality and health weather indices for wellness and operations automation, handle tropical storm and hurricane tracking for disaster risk management, access agricultural weather products and growing degree day data for precision agriculture, retrieve UV index and outdoor conditions for health and activity planning automation, manage global weather coverage for international operations and supply chain weather risk, and integrate AccuWeather with logistics, retail, agriculture, and outdoor operations platforms.

Model-agnostic, async-first Python agent framework with built-in team orchestration, multimodal support, memory, and persistent storage — the official successor to Phidata.

Database migration tool for SQLAlchemy. Generates and applies schema migration scripts to evolve database schema over time. Creates versioned migration files with upgrade/downgrade functions. Detects schema differences between SQLAlchemy models and current database state (autogenerate). The standard migration tool for SQLAlchemy-based Python applications.
