Run Capture The Flag events that cannot be faked.

Hosts create timed events, publish challenges and monitor submissions. Players register, join teams, submit flags and climb a leaderboard computed entirely from trusted server-side data.

Design principles

Built for correctness before convenience

No client input can influence event timing, scoring, ranking or flag validation. Everything a competitor sees is derived on the server.

Event-first

Challenges belong to an event. Nothing is globally playable.

Server-authoritative

Time, score, rank and solves are determined server-side only.

Isolated by design

Challenge workloads never share the application runtime.

Auditable

Every privileged action is authorized and recorded.
