EasyCTF Platform


This is a genericized version of EasyCTF 2014, and can be used as a backend for hosting CTF competitions. This was based on picoCTF 2013's CTF-Platform.

Getting Started

  1. Clone the repo and run npm install to install dependencies.
  2. Modify the options in api/common.js.
  3. Navigate to the directory using some kind of shell and run node app to start the server.
  4. The server will listen on port 3000 by default unless you specify a different port in the environmental variables.


This platform is written in Node.js. Therefore, it is quite obvious that you need to have Node.js installed on your system in order to run this server. The node dependencies are all included in the repo, but if you have any trouble with those, simply run npm install --save inside the directory, since all of the packages should be listed in package.json.

I'd recommend using a Unix-based computer (that includes you, Macs 😄 ) to run this, however using Windows is perfectly acceptable. In fact, this platform was written and tested more on a Windows computer than on Linux.


Like picoCTF's platform, this server consists of many static HTML files that make AJAX (asynchronous) requests to an API. The API does not need to be launched separately; it is built into the server.


This platform requires a MongoDB server. MongoDB has many advantages to SQL, and if you want a full list of those, Google it. The following collections exist in the database:

  • accounts (store user information)
  • problems (store problem information)
  • reset_password (password reset requests)
  • shell_accounts (for if you want to have a shell)
  • submissions (store submission information)

Sample problem information can be found in the docs folder in this repo (TODO).


It is strongly recommended that you use Heroku. Heroku is simple to set up, runs on Git, and has many partners that will give you exclusive deals on their products (such as email servers, DNS servers, etc.). This platform is ready to push to Heroku directly.

$ (git add, git commit)
$ heroku create
$ git push heroku master
$ heroku ps:scale web=1 # Ensure at least one web process is running


Platform for hosting CTFs. Node.js is the only real dev language.
