## What it is
Remark42 is a self-hosted, privacy-focused comment engine written in Go that can be embedded into blogs and articles. It supports social and email login, nested comments, moderation, notifications, and runs as a single lightweight binary or Docker container with no external database.

## Use cases
- add comments to a blog without Disqus
- self-host a privacy-friendly comment system
- replace Disqus with a lightweight comment engine
- embed a comments widget on a static site
- moderate and block commenters on my site
- let readers log in with GitHub or Google to comment
- migrate comments from Disqus or WordPress

## When to choose
- you want a self-hosted, privacy-respecting comment system with no tracking
- you need a lightweight single-binary or Docker deployment without external databases
- you want social login, email login, moderation, and notifications out of the box

## When to avoid
- you need a fully hosted SaaS comment service with zero server maintenance
- you require heavy customization of the comment backend beyond what the API offers
- you need real-time threaded chat rather than article comments

## Facets
- artifact type: service
- maturity: stable
- function: auth, http-server, webhook, email, file-upload, markdown
- domain: web-development, self-hosted, privacy, cms
- platform: self-hosted, windows, cross-platform
