CTF-OS is a preconfigured virtual machine image purpose-built for Capture The Flag (CTF) competitions, bundling a curated set of security and puzzle-solving tools on a tuned Windows 10 base with WSL2 Ubuntu and Arch subsystems. It lets players spin up a ready-to-use, isolated environment without polluting their host machine.

Use cases

• set up a ctf competition environment quickly
• avoid installing ctf tools on my main machine
• get a preconfigured virtual machine for capture the flag
• beginner-friendly ctf toolkit with pwn and web tools
• isolated vm for security ctf challenges
• download a ready-made ctf os image

When to choose

• you want an out-of-the-box CTF environment without manually installing dozens of tools
• you need to keep CTF software isolated from your host system
• you are a CTF beginner who wants a curated toolset matching the Hello-CTF toolkit
• you occasionally compete in industry CTF events and don't want permanent tool installs

When to avoid

• you need a general-purpose penetration testing distribution like Kali for real-world engagements
• you require a native Linux CTF environment (Linux builds are still in progress)
• you run Apple Silicon Macs (ARM adaptation is still a TODO)
• you want fully automated or incremental updates, which are not yet implemented
