A hosted comment widget saves you from building moderation, spam filtering and accounts. Disqus 882 is the classic drop-in snippet, stores comments on its own servers and earns its money mainly from advertising, so expect ads and tracking on your pages. Developer blogs lean toward two MIT-licensed tools that keep each page's thread in your own GitHub 29 repository, with readers signing in through GitHub: giscus 107,829 (https://giscus.app/ 107,829 ) uses GitHub Discussions and promises "no tracking, no ads, always free", while utterances 9,694 (https://github.com/utterance/utterances 9,694 ) uses GitHub Issues and has seen no commits since August 2024.
