Privacy

Remark42 is trying to be very sensitive to any private or semi-private information.
Authentication is requesting the minimal possible scope from authentication providers and all extra information returned by them is immediately dropped and not stored in any form.
Generally, Remark42 keeps user ID, username and avatar link only. None of these fields exposed directly - ID and name hashed, avatar proxied.
There is no tracking of any sort.
Login mechanic uses JWT stored in a cookie (HttpOnly, secured). The second cookie (XSRF_TOKEN) is a random ID preventing CSRF.
There is no cross-site login, i.e., user's behavior can't be analyzed across independent sites running Remark42.
There are no third-party analytic services involved.
Users can request all information Remark42 knows about them and receive the export in the gz file.
Supports complete cleanup of all information related to user's activity by user's "deleteme" request.
Cookie lifespan can be restricted to session-only.
All potentially sensitive data stored by Remark42 hashed and encrypted.

giscus

A comments system powered by GitHub Discussions. Let visitors leave comments and reactions on your website via GitHub! Heavily inspired by utterances.

Open source. 🌏
No tracking, no ads, always free. 📡 🚫
No database needed. All data is stored in GitHub Discussions.
Supports custom themes! 🌗
Supports multiple languages. 🌐
Extensively configurable. 🔧
Automatically fetches new comments and edits from GitHub. 🔃
Can be self-hosted! 🤳

Note
giscus is still under active development. GitHub is also still actively developing Discussions and its API. Thus, some features of giscus may break or change over time.

How it works

When giscus loads, the GitHub Discussions search API is used to find the Discussion associated with the page based on a chosen mapping (URL, pathname, <title>, etc.). If a matching discussion cannot be found, the giscus bot will automatically create a discussion the first time someone leaves a comment or reaction.

To comment, visitors must authorize the giscus app to post on their behalf using the GitHub OAuth flow. Alternatively, visitors can comment on the GitHub Discussion directly. You can moderate the comments on GitHub.

how it works

When Utterances loads, the GitHub issue search API is used to find the issue associated with the page based on url, pathname or title. If we cannot find an issue that matches the page, no problem, utterances-bot will automatically create an issue the first time someone comments.

To comment, users must authorize the utterances app to post on their behalf using the GitHub OAuth flow. Alternatively, users can comment on the GitHub issue directly.

FAQ

Compared to Disqus

Cusdis is not designed to be a complete alternative to Disqus. It's aim is to implement a minimalist and embeddable comment system for small websites (such as your static blog).

Given below are the pros and cons of Cusdis:

The SDK is lightweight(~5kb gzipped).
Cusdis doesn't require your user to sign in to make a comment.
Cusdis doesn't use cookies at all.

Cons

Cusdis is on the early stages of its development.
There is no spam filter, hence, you will have to manually moderate your comment section and comments won't be displayed until you approve them.
Disqus is a company, we aren't.
