FBCTF is a self-hosted platform for running Jeopardy and King of the Hill style Capture the Flag security competitions. It supports team registration, challenge administration, and scoring for events from a few participants to several hundred.

Use cases

  • host a capture the flag competition
  • run a jeopardy-style ctf event
  • organize a king of the hill hacking competition
  • set up a ctf platform for a security class
  • run an online or in-person ctf for hundreds of teams

When to choose

  • you need a proven, full-featured platform to host a CTF competition
  • you want both Jeopardy and King of the Hill game modes
  • you can self-host on Linux with HHVM

When to avoid

  • you need an actively developed project - it is archived by Facebook
  • you prefer a modern PHP/Python stack instead of Hack/HHVM
  • you need commercial use - it is licensed CC BY-NC 4.0
