Open the Builder and describe the challenge you want — theme, difficulty, vibe.

Roota's AI writes the story, the fake site, the challenges and the flags. You can iterate in chat.

Click Publish to push to roota.dev/@you/your-slug. Pick a cover and (if needed) tell players how to run a backend locally.

Players can play in the browser, or download the ZIP and run it themselves.

Every CTF can be exported as a ZIP. Players just unzip and open index.html.

If your CTF needs a backend, set the toggle in Publish and provide commands like npm install && npm start. Players see them on the public page.

Open /dashboard/your-slug to see plays per day, captures per challenge, average solve time and a leaderboard.

The Public builds page lists community CTFs by popularity, trending and newest.

Roota CTFs target fictional systems. They are educational sandboxes — never use them against real services or people.
