CTFtime

CTFtime is a community-maintained online platform that tracks and aggregates results from Capture The Flag (CTF) competitions. It provides a centralized database of teams, events, and scores and offers both live scoreboards during events and a historical archive of past results. The site aims to standardize the presentation of CTF results across different competition formats and to facilitate comparison of performance across events and over time.

Data and scoring: CTFtime collects submissions from participating CTF platforms, validates solutions, and computes team scores and rankings. It supports multiple scoring formats used by various organizers and presents data in a consistent, searchable interface. The platform also stores event metadata such as start and end times, format, and problem sets, along with historical results and team affiliations.

Features: event pages with schedules, rules, and problem lists; team pages showing rosters and historical performance; a live scoreboard that updates during events; a searchable database of teams and events; export options and an API for programmatic access.

Organization and use: The project is volunteer-driven and maintained by contributors from the information security community. Data quality relies on organizers and teams to submit and verify results, with community moderation to resolve discrepancies.
