4 plugins to add comments to your Gatsby.js blog

Integrating a comment system into a Gatsby blog can enhance engagement, boost SEO, and provide valuable reader feedback, with several free plugin options available including Disqus, GitTalk, CommentBox, and GraphComments. Disqus is known for its robust authentication and media embedding capabilities but may affect page load speed, while GitTalk offers serverless performance and GitHub-based data storage, though it lacks built-in moderation. CommentBox focuses on privacy with a free tier capped at 100 comments, while GraphComments provides a community system with extensive features but limits free data loads to one million per month. Each plugin has its pros and cons, with the choice ultimately depending on individual preferences regarding control, performance, and user interface.
