## What it is
A thread-safe fork of React Helmet for managing document head tags (title, meta, link) in React 16+ apps, using a HelmetProvider to encapsulate state per request. It supports server-side rendering and adapts to React 19's built-in head hoisting.

## Use cases
- manage meta tags and title in a react app
- server-side render head tags per request
- set canonical links and SEO tags in react
- thread-safe helmet for async SSR
- manage document head in react 16-18
- add open graph tags to react pages

## When to choose
- you need per-request head state in SSR with async rendering
- you're on React 16-18 and need Helmet features like titleTemplate or prioritizeSeoTags
- you need htmlAttributes/bodyAttributes manipulation

## When to avoid
- you're on React 19+ and only need basic title/meta hoisting
- you don't need SSR context serialization or onChangeClientState

## Facets
- artifact type: library
- maturity: active
- function: ssr, frontend-framework, templating
- domain: web-development, frontend
- platform: browser
- tags: react, react-helmet, meta-tags, document-head, seo, thread-safe, ssr, nodejs, web-server
