giscus
Comments system that stores a site's comments as GitHub Discussions and shows them on the page through a script tag.
giscus is a comments system that keeps a site’s comments as GitHub Discussions. The creator names a public repository, and the discussion for each page is found through a mapping the configuration sets, such as the page pathname or title. When no discussion matches, the giscus bot creates one the first time someone comments or reacts.
The creator adds a script tag to the site’s template, and the comments load into the page inside an iframe. Visitors post by authorizing the giscus GitHub App, or they comment on the discussion on GitHub directly. Self-hosting is the other route: the creator registers a GitHub App and deploys the giscus web app.
Worth knowing
The comments live on GitHub. Visitors need a GitHub account to post, the repository has to be public, and Discussions has to be enabled on it.
