## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 1910, "days_push": 10, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated archive of Capture The Flag (CTF) competition challenges organized by event and year, with links to writeups and CTFtime event pages. It covers many well-known CTFs such as 0CTF, spanning multiple years of challenge files.

## Use cases
- practice ctf challenges from past competitions
- find writeups for old ctf events
- download pwn and reverse engineering challenge binaries
- prepare for a capture the flag competition
- study past ctf cryptography and web challenges
- build a local ctf practice environment

## When to choose
- you want historical CTF challenge files for practice or research
- you need writeup links for specific CTF events and years
- you are training a team or learning security skills through CTFs

## When to avoid
- you need a CTF hosting platform to run your own event
- you want guided tutorials rather than raw challenge archives
- you need a vulnerability scanner or offensive security tool

## Facets
- artifact type: dataset
- maturity: active
- function: security, developer-tools
- domain: security, education, tutorials
- platform: cross-platform
- tags: ctf, capture-the-flag, challenges, writeups, archive, pwn, reverse-engineering, cryptography, web-security
