React Helmet vs Stencil: What are the differences?
Developers describe React Helmet as "A document head manager for React". This reusable React component will manage all of your changes to the document head with support for document title, meta, link, style, script, noscript, and base tags. On the other hand, Stencil is detailed as "A reusable web component generator". Stencil combines some of the best features from traditional frameworks, but outputs 100% standards-compliant Custom Elements, part of the Web Component spec.
React Helmet and Stencil are both open source tools. It seems that React Helmet with 10.9K GitHub stars and 441 forks on GitHub has more adoption than Stencil with 6.03K GitHub stars and 354 GitHub forks.
