CTFd is heavily integrated withMajorLeagueCyber. MajorLeagueCyber (MLC) is a CTF stats tracker that provides event scheduling, team tracking, and single sign on for events.

By registering your CTF event with MajorLeagueCyber users can automatically login, track their individual and team scores, submit writeups, and get notifications of important events.

To integrate with MajorLeagueCyber, simply register an account, create an event, and install the client ID and client secret in the relevant portion inCTFd/config.py or in the admin panel:
