## Health v2 (maintenance only)
Score: 55/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 50, release rhythm 35, longevity 100
- inputs: {"age_days": 2207, "days_push": 300, "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 awesome-list of header-only C++ libraries, organized by category (parsing, testing, serialization, GUI, etc.) with stars, descriptions, and licenses. It serves as a discovery resource rather than a usable software artifact itself.

## Use cases
- find a header-only C++ library
- discover single-header C++ libraries for my project
- curated list of modern C++ libraries
- header-only alternatives to boost
- find C++ testing or serialization libraries
- awesome C++ library list

## When to choose
- you want to avoid build/link complexity with header-only dependencies
- you're browsing for well-known C++ libraries by category
- you want a quick reference of popular single-header libraries

## When to avoid
- you need a runnable tool or library rather than a list of links
- you need non-header-only C++ libraries
- you need guaranteed up-to-date or vetted library recommendations

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: developer-tools, awesome-lists, cross-platform
- platform: cross-platform, cpp
- tags: awesome-list, header-only, cpp, curated-list, libraries
