jailCTF 2025

This is the second jailCTF event. Unlike traditional CTFs, this event has a large focus on "jail" challenges which ask players to escape out of a code sandbox with some set of restrictions applied. Categories here aren't traditional here either, with pyjail, esolang, and other mainstream languages as categories (js, perl, ruby, c, etc). Come and have fun in jailCTF!
