Launch the lab

Open it in the Cyber CTF launcher, or run it yourself with Docker Compose.

Open in the launcher Source code

›Run it manually

$git clone https://github.com/CyberCTF/skf-cmd && cd skf-cmd && docker compose up -d

Without the launcher, the lab uses its public development evidence: great for practice, but it won't complete the lab.
