## What it is
GZ::CTF is an open-source Capture The Flag (CTF) competition platform built on ASP.NET Core with a React frontend. It supports static and dynamic challenges with per-team flag generation, containerized challenges, dynamic scoring, leaderboards, and cheat detection.

## Use cases
- host a CTF competition for my school or company
- run a cybersecurity training event with dynamic flags
- deploy container-based CTF challenges on kubernetes
- organize a jeopardy-style hacking contest with a leaderboard
- self-host a CTF platform with cheat detection and traffic logging

## When to choose
- you need a full-featured, self-hosted CTF platform with dynamic per-team flags
- you want containerized challenge deployment on Docker or Kubernetes
- you need high-concurrency support for large competitions

## When to avoid
- you only need a simple static quiz or learning platform without competition features
- you cannot operate Docker/Kubernetes infrastructure
- you require downgrade migrations between versions, which are unsupported

## Facets
- artifact type: application
- maturity: active
- function: web-framework, http-server, container-orchestration, auth, monitoring
- domain: security, self-hosted, web-development, education
- platform: self-hosted, cross-platform
- tags: ctf, capture-the-flag, aspnet-core, react, competition-platform, dynamic-flags, leaderboard, cheat-detection, docker, kubernetes, web-server
