Run events
Host CTFs solo or as leagues with seasons. Organise challenges by category, points, and framework mappings — or run a seeded single-elimination bracket.
Competitive CTF platform
The career record for capture-the-flag.
Run events, import results from any scoring platform, and turn every solved challenge into verifiable, NIST NICE-mapped skill evidence — for players, teams, and recruiters.
Everything an event needs
From scoreboard to skill record
Import from anywhere
Bring final results from any scoring platform via our open results standard. Players are auto-matched; unclaimed results stay claimable. No platform lock-in.
Verifiable skills
Every solve maps to the NIST NICE framework, building an evidence-backed profile of what a player can actually do — not just a point total.
Player profiles
Career stats, playstyles, community-endorsed skills, and writeups in one shareable profile. Follow players and teams to track their results.
Teams & leagues
Register rosters, track attendance and score history, and aggregate standings across a whole league season.

Opt in to recruiting and let vetted recruiters discover you by demonstrated skill — your CTF record doing the talking.
