Utterances review
A free, open-source website comments widget for sites already centered on GitHub Issues.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Utterances adds an embeddable comments widget to blogs, wikis, and other websites, with GitHub Issues serving as the discussion store. It suits personal sites and small projects whose owners already organize work in GitHub and want comments tied to page-specific issues. A page can map to an issue by URL, pathname, or title, and the bot can create a matching issue when the first comment arrives. Commenters authorize through GitHub OAuth, so the discussion flow is closely tied to GitHub rather than a standalone account system.
That GitHub connection is both the product’s defining strength and its main ecosystem constraint. Comments are GitHub issue comments, and page mapping can be configured along with issue labels; site owners can also choose a theme, including a dark theme. This structure can be a natural fit for a site whose owner already manages discussion in GitHub. It is less suitable for a publisher seeking a commenting service independent of GitHub, since the issues remain the underlying discussion space and commenter authorization depends on GitHub OAuth.
Utterances is free and open source, with the vendor describing the project as operating without ads or tracking. Moderation is handled through linked GitHub issues; dedicated moderation tools are not documented. The product’s focused model may work well when basic issue-based comment management is sufficient, but buyers looking for a broader commenting system should compare alternatives that offer dedicated moderation. Choose Utterances for a GitHub-centered personal site and configurable page-to-issue mapping; look elsewhere if GitHub should not be part of the commenting experience.
