Cryptofeed

Cryptofeed is an open-source Python library that connects to cryptocurrency exchange market-data feeds, normalizes events such as trades and order-book updates, and delivers them to registered callbacks or supported backends.

Practical overview

When it fits

Use Cryptofeed when a Python application needs a common event-handling layer across supported exchange feeds, or when exchange data must be delivered to callbacks, storage systems or a replayable capture.

Who it is for

  • Python developers building applications that ingest market data from multiple cryptocurrency exchanges.
  • Analytics and data-pipeline teams that need standardized exchange events for processing or storage.
  • Researchers or developers recording exchange feeds for later replay.

Documented uses

  • Collect trade, ticker, book and other supported public market-data events.
  • Pass standardized updates to asynchronous client callbacks.
  • Aggregate selected exchange feeds into a synthetic NBBO update.
  • Route events through supported storage or messaging backends.
  • Record feed data to pcap files for later replay.
Before you choose

Requirements & limits

The project is open source and available from PyPI. Its README specifies Python 3.13 or later and displays an AGPL license badge linked to a license file.

  • WebSockets are used where available; REST polling is used otherwise.
  • Supported exchanges and channels vary, and some feeds provide only partial L2 or L3 order-book depth.
  • Callbacks must be asynchronous unless wrapped with the provided ExecutorCallback for synchronous handling.
  • Optional dependencies depend on the selected backend.
  • Trade events report the taker’s side, including for exchanges that report the maker’s side.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Cryptofeed from PyPI

Install the library in a Python environment before configuring exchange feeds or storage backends.

Before you start

  • Python 3.13 or later
  • A Python environment with pip

Steps

  1. Install the package with pip install cryptofeed.

  2. If you need the optional dependencies for all backends, install with pip install cryptofeed[all].

Expected outcome

Cryptofeed is installed; you can proceed to configure FeedHandler subscriptions and callbacks in your application.

Guide limitations

  • Backend-specific dependencies may be installed individually instead of using the all-dependencies extra.
  • This installation procedure does not configure or run an exchange feed.
