Packages

Real-time REST and WebSocket API for stocks, forex, and cryptocurrency data, plus news, earnings, insider transactions, economic indicators, and sentiment analysis.

MCP server for fetching current stock prices and key data for symbols across global markets. Enables AI agents to look up the latest stock prices, market data, and financial metrics for listed companies — supporting financial research, portfolio tracking, and market analysis workflows.

Instant GraphQL and REST APIs over databases (Postgres, MySQL, SQL Server, MongoDB) with role-based permissions, realtime subscriptions, and event triggers.

Enhanced Solana RPC provider with additional APIs beyond standard JSON-RPC: Digital Asset Standard (DAS) API for NFT/token metadata, transaction parsing API, webhook event notifications, and historical transaction data. Used as the primary Solana infrastructure for most production dApps. Significantly more useful than raw Solana RPC due to enriched data.

Asynchronous web framework for Kotlin built by JetBrains. Ktor uses Kotlin coroutines for non-blocking I/O, providing a lightweight and flexible HTTP server and client. Unlike Spring Boot, Ktor is micro-framework-style — you compose exactly what you need (routing, serialization, auth, compression). Used for building Kotlin REST APIs, microservices, and HTTP clients. Both server and client in one framework.

Python-based web UI framework that wraps Quasar (Vue.js) components with a Python API. NiceGUI lets you build full web UIs purely in Python with reactive updates via WebSocket. Unlike Streamlit (which re-runs scripts), NiceGUI maintains persistent connections and component references — closer to React's model but in Python. Originally designed for robotics control panels (Zauberzeug makes autonomous vehicles), it works well for any real-time monitoring or control interfaces.

Open-source authorization library and cloud service that uses the Polar policy language to define and enforce fine-grained RBAC and ReBAC access control in application code or via a hosted API.

Fast async Python ORM with a focus on type safety and developer experience — supports sync and async usage, generates migrations automatically, and provides a FastAPI/Starlette-native experience. Piccolo features: Table subclasses for models (class Agent(Table): name = Varchar()), query builder API (await Agent.select().where(Agent.active == True).run()), migrations via piccolo migrations new + piccolo migrations run, Piccolo Admin (React-based admin UI), and REST endpoint generation via piccolo_api. Uses asyncpg under the hood for PostgreSQL. CLI tools for project creation, schema inspection, and migration management. Designed as async-first alternative to SQLAlchemy for modern Python API services.

HTML-first JavaScript framework designed for instant page load times. Qwik introduces 'resumability' — instead of hydrating a React-like app (downloading and executing all JavaScript before interactivity), Qwik serializes component state into HTML and resumes execution lazily in the browser only when needed. This achieves near-zero JavaScript on initial load. Created by Builder.io (Miško Hevery, Angular creator). Qwik City is the full-stack meta-framework (like Next.js for Qwik).

Go plugin for protoc that generates a reverse-proxy server translating RESTful JSON API calls into gRPC calls. Add HTTP annotations to .proto files and grpc-gateway generates a REST endpoint that proxies to the gRPC service. Also generates OpenAPI 2.0/3.0 docs. Used when you need both gRPC (for microservice-to-microservice) and REST (for public APIs, browsers) from the same service definition.

AWS-native Python microframework for building serverless applications on Lambda, using Flask-like decorator routing (@app.route) with automatic IAM role generation and native integrations for DynamoDB, SQS, S3, and SNS events.

LLM evaluation platform that combines dataset versioning, prompt management, LLM-as-judge scoring functions, and real-time tracing under a projects/experiments/datasets hierarchy with CI pipeline integration via CLI.

Converts text to lifelike speech with voice cloning capabilities, supporting 29 languages with streaming audio output.

Ultra-minimalist Python WSGI/ASGI REST framework using a Resource class pattern with responder methods (on_get, on_post), optimized for low overhead and high request throughput.

High-scale, cost-efficient distributed tracing backend from Grafana Labs. Tempo stores traces directly in object storage (S3, GCS, Azure Blob) with no indexing — making it dramatically cheaper than Jaeger or Zipkin for high-volume trace storage. Integrates natively with Grafana for trace visualization and supports trace-to-log and trace-to-metric correlation. Accepts OTLP, Jaeger, Zipkin, and OpenCensus trace formats. Designed as the tracing component of the Grafana LGTM stack (Loki + Grafana + Tempo + Mimir).

Open-source Agent Teams system that deploys coordinated AI agent teams within 5 minutes. A Manager Agent orchestrates Worker agents with all communication visible in Matrix IM. Workers never hold real API keys — the Higress MCP Gateway manages credentials separately for security.

Lightweight Python task queue library backed by Redis (or SQLite/in-memory) for running background jobs, periodic scheduled tasks, and distributed work queues. A simpler alternative to Celery for Python projects.

A development framework for building enterprise-grade MCP servers by automatically converting FastAPI endpoints into AI-callable MCP tools, with dependency injection, service interface separation, and built-in testing support.

Modal is a serverless Python cloud compute platform that lets agents deploy and invoke Python functions (including GPU-accelerated ML workloads) as scalable serverless endpoints, batch jobs, and scheduled tasks — without managing infrastructure.

Multi-cloud serverless deployment framework that packages and deploys Lambda, Azure Functions, and GCP Cloud Functions via serverless.yml configuration.
