I made this one for Brucon and North Star, about an AI gaining consciousness.
The code is open source but the online version isn’t working right now (supabase timeout, don’t recommend that one), but hit me up and I’ll get it running.
Two skins on the same engine — a robotics theme and a Star Wars one — with the usual CTF categories (web, crypto, reverse, forensics, pwn, misc, terminal), teams, a leaderboard, and an admin tier. A few challenges live off the website entirely, spoken aloud or planted on hardware at the venue, not just in the code.
Rebels CTF is the name for where I want to take it: prove it once, then run it as a touring thing — one city, then the next.
