Packages

Provides real-time, forecast, and historical weather data along with astronomy information, air quality indices, and severe weather alerts for any location worldwide.

Extended Python pickling for distributed computing — serializes Python objects that standard pickle cannot, including lambdas, closures, locally defined functions, and class definitions. cloudpickle features: cloudpickle.dumps()/loads() API compatible with pickle, serializes lambda functions (not picklable with standard pickle), closures capturing local variables, inner functions, dynamically defined classes, generator functions, functools.partial with lambda args, and is used internally by Ray, Dask, PySpark, and joblib. Essential for sending Python callables across process boundaries.

The official Redis client library for Go. go-redis (formerly go-redis/redis) provides a type-safe API for all Redis commands, connection pooling, Redis Cluster and Sentinel support, pipelining, transactions (MULTI/EXEC), Pub/Sub, and Redis Streams. The de-facto standard Go Redis client used in production systems.

MCP server that allows AI assistants to create, manage, and monitor n8n workflows through natural language. Supports multi-instance management across dev/staging/production environments with 17 tools covering workflow CRUD, execution monitoring, tag management, and credential handling.

MCP server that helps AI models understand your local Vite/Nuxt application better during development. Provides two packages: nuxt-mcp-dev (Nuxt module) and vite-plugin-mcp (Vite plugin) that expose app context to MCP-connected AI assistants.

MCP server providing AI models with full CRUD access to Obsidian knowledge bases, including note management, folder operations, full-text search, precision PATCH editing at heading/block level, auto-backlinking, and AI-powered vault analysis. Uses a dual API strategy with Obsidian REST API and filesystem fallback.

Job queue for Node.js that uses PostgreSQL as the backing store. pg-boss leverages PostgreSQL's SKIP LOCKED for efficient job dequeuing and uses the same database as your application — no separate Redis infrastructure required. Supports job scheduling, delayed jobs, recurring jobs (cron), job completion callbacks, retry with exponential backoff, and concurrency control. Ideal for applications already using PostgreSQL.

Modern Python PostgreSQL adapter — the successor to psycopg2 with native async support, binary protocol, and improved type system. psycopg3 features: async/await API (AsyncConnection, AsyncCursor), synchronous API with same interface, server-side parameters (not string interpolation), binary protocol for performance, row_factory for dict/dataclass results, connection pools (AsyncConnectionPool), COPY support (copy.write_row()), pipeline mode for batched queries, adapters for custom Python types, and native PostgreSQL COPY protocol. Required for FastAPI/async agent backends using PostgreSQL.

Fully automated version management and package publishing. semantic-release analyzes commit messages (using Conventional Commits format) to determine the next version number, generate a changelog, create a git tag, publish to npm/GitHub/other registries, and create a GitHub Release — all automated in CI with zero manual steps. 'If your commits are descriptive, your release process should be automatic.'

Extensions to Go's standard database/sql package. sqlx adds struct scanning (DB.Get, DB.Select), named queries (:param syntax), IN clause expansion, and StructScan to avoid manual Scan() field-by-field mapping. A thin but highly practical layer over database/sql — not a full ORM, just ergonomic SQL with struct binding. The most common Go database helper library for teams that want raw SQL with less boilerplate.

MCP server enabling interaction with TickTick task management through Claude and other MCP clients, supporting full CRUD on tasks and projects with GTD framework tools and date-based queries.

Codat financial data API for fintech lenders, B2B SaaS companies, and banks to connect to SMB accounting software, banking data, and commerce platforms through a single unified API. Enables AI agents to manage accounting software connections (QuickBooks, Xero, Sage, FreshBooks) for SMB financial data aggregation automation, handle real-time profit and loss, balance sheet, and cash flow statement retrieval for underwriting automation, access accounts payable and receivable aging for working capital analysis automation, retrieve bank transaction feeds and reconciliation data for cash flow monitoring automation, manage commerce platform data (Shopify, Amazon, Square) for revenue-based lending automation, handle bill and invoice synchronization for AP/AR workflow automation, access payroll data connectivity for small business cash flow automation, retrieve tax filing data for financial health scoring automation, manage data refresh scheduling and webhook delivery for continuous financial monitoring automation, and integrate Codat with lending platforms, accounting software, and open banking for end-to-end SMB financial data infrastructure.

Containerized build tool that combines Dockerfile and Makefile into a unified Earthfile syntax. Every build step runs in a container, making builds reproducible across local dev, CI, and CD environments. Earthly eliminates 'works on my machine' CI failures by ensuring the same containerized environment everywhere. Supports parallelism, caching, and composable build targets. Earthly Satellites (cloud) provides remote build execution and shared caching.

Easyship REST API for multi-carrier shipping rate shopping and fulfillment platform. Enables AI agents to compare shipping rates across 250+ couriers globally, handle shipment label generation and booking, access customs documentation and HS code classification, retrieve duty and tax calculation for cross-border shipments, manage shipment tracking across all carriers, handle returns management and label generation, access packaging optimization and box selection, retrieve shipping analytics and cost reporting, manage warehouse and fulfillment workflows, and integrate multi-carrier shipping with e-commerce platforms (Shopify, WooCommerce, Amazon).

React-based static site generator with a powerful GraphQL data layer. Gatsby pulls data from multiple sources (CMS, APIs, files) at build time via a unified GraphQL layer and generates a static React site. Known for its plugin ecosystem (1000+ plugins), image optimization, and performance features. Widely used for marketing sites, blogs, documentation, and e-commerce. Gatsby acquired by Netlify in 2023.

Python WSGI HTTP server. The standard production server for synchronous Python web applications (Flask, Django). Pre-fork model spawns worker processes to handle concurrent requests. Sits behind nginx/caddy as a reverse proxy. Simple configuration and high reliability make it the default choice for WSGI app deployment.

Cross-platform GUI library for Rust inspired by Elm architecture. Uses a Model-Update-View pattern where the entire UI is defined as a pure function of application state. Renders with wgpu (GPU-accelerated) and targets desktop (Linux, macOS, Windows) and web (via WASM). Iced is more opinionated than egui with a declarative reactive architecture vs immediate mode.

Zero-downtime container deployment tool using SSH and Docker — no Kubernetes required. Kamal (formerly MRSK) deploys Docker containers to bare metal or VMs via SSH with blue/green deployments, rolling updates, load balancer integration (Traefik), and remote exec capabilities. Created by Basecamp/37signals as an alternative to Heroku without cloud PaaS pricing. YAML-based deployment config checked into git. CLI for deployment management with programmatic access via Ruby API.

Ultra-lightweight, security-first service mesh for Kubernetes. Linkerd uses a Rust-based micro-proxy (not Envoy) injected as sidecars, providing automatic mTLS, traffic shifting, retries, timeouts, and observability with minimal overhead. Significantly simpler than Istio — focuses on core security and reliability features without the full traffic management complexity. CNCF graduated project. Known for its 'boring is good' philosophy: fewer features than Istio but much lower operational complexity.

French LLM provider offering Mistral Small/Medium/Large and Mixtral mixture-of-experts models via an OpenAI-compatible REST API.
