Install

The easiest way to get started is to use a Hosted CTFd instance.

For self-hosted installations, check out the CTFd docs for deployment options and the Getting Started guide.

Below is a summary of a few options for self-hosting CTFd:

Docker

You can use Docker Compose with the following command from the source repository:

docker compose up

To use the auto-generated Docker images directly:

docker run -p 8000:8000 -it ctfd/ctfd

De

1. Install uv and run uv sync to create a with the dependencies installed.
- You can also install into an existing en with pip install -r requirements.txt, which is generated from uv.lock.
2. Modify CTFd/config.ini to your liking.
3. Use uv run serve.py or uv run flask run in a terminal to drop into debug mode.

Managed Hosting

Looking to use CTFd but don't want to deal with managing infrastructure? Check out the CTFd website for managed CTFd deployments.

MajorLeagueCyber

CTFd is heavily integrated with MajorLeagueCyber. 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 indi 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 in CTFd/config.py or in the admin panel:
