    Today, we’re releasing rCTF v2, an open-source platform for hosting cybersecurity capture-the-flag competitions.
    The signature rCTF wordmark, white on black with red accenting. A red stylized “v2” sits slanted on the bottom-right side.
    A screenshot of rCTF's matrix-style leaderboard displays teams as rows, challenges as columns, and their intersection as the team's solve status on that challenge.

Each team has a custom avatars, country flag, and tagline. A sparkline shows the team's scoring activity.

The top-left corner of the leaderboard displays a line chart, plotting the visible teams against each other.
    A screenshot of the rCTF's challenge listing. It is panel-style; the left side displays all challenges within the event, while the right side displays the details of a particular selected challenge (the challenge's description, attachments, and any custom instancing).
    The platform's admin view allows for viewing and auditing of the submission logs from all teams. A complex filtering system allows filtering against (non-exhaustively) challenge names, submission results, and time intervals.
