Cryptofeed

If you're building anything that needs real-time crypto market data, this handles the messy parts. It connects to 40+ exchanges via WebSocket, normalizes all their different formats into consistent structures, and lets you process trades, order books, and tickers without writing exchange-specific code. The NBBO feature is solid for aggregating best prices across venues. You can pipe data directly into Redis, Kafka, Postgres, or a dozen other backends without custom plumbing. It's actively maintained, Python 3.8+, and the API is straightforward. The kind of tool that saves you from reinventing exchange connectors when you just want to get to the actual trading logic.
