What is a CTF?Design your own questions. Understand where your students excel and where they might need to improve. Creating light competition drives users to out-do one another on the public scoreboard and share techniques.
Our custom designed challenge workflow makes it easy to deploy your Docker based challenges. It's as easy as docker push.
Visualize your users with skill graphs. With easy to use visualizations, you can quickly infer the state of a team without getting into the nitty gritty.

Easily deploy and manage CTF challenges using our hosted platform, with tools you already know.
First we create a simple challenge that just emits our flag on connect.
It must include a Dockerfile which attempts to EXPOSE a port.
Finally, you should be able to build your docker image with docker build -t project
Create your challenge, and the service in CTFd UI.
Push your docker image to our registry, and your service will be deployed - just like magic.
CTFd offers organizers unmatched flexibility and ongoing improvements, thanks to active development, open source contributions, and customizable plugins and themes.
With all the visualization in CTFd you'll know what's going on with just a glance.
With its HTML editor, you can create entire pages inside of CTFd. Need to share lots of links? Make an FAQ? A contact page? No problem.
All you need to use to run your very own Capture The Flag is a web browser. Just use the built in administration panel and say goodbye to database queries.
Hacking is hard work. If your users are stuck you can setup hints for them to get unstuck.
With the Import/Export feature, you can save your CTF and reuse all your hard work.
No clutter makes the default theme of CTFd a beauty without being opinionated.
See what other organizations have said about CTFd.
“We struggled with our own infrastructure for a few years before switching to CTFd. We anticipated that the slick interface, easy configuration, and stability would be a big win for us, but what surprised us was what we weren’t expecting: our data got better. CTFd has made it easier for us to scout blue-chip prospects and elite veteran tech talent for our company.”
“No longer are you bogged down with the task of creating the scoring, registration, administration, challenge modals, and all auxiliary applications, you can focus on what matters; challenges and learning objectives!”
