Deploy and Host Remark42 on Railway

Remark42 is a self-hosted, lightweight, and privacy-focused comment engine. It serves as a robust alternative to proprietary systems like Disqus, featuring social logins (Google, GitHub, Twitter, etc.), Markdown support, and moderation tools. It is designed to be easy to integrate into static websites and blogs without tracking user data.

About Hosting Remark42

Hosting Remark42 on Railway requires running a Docker container and attaching a Persistent Volume to store the embedded database (BoltDB) and user avatars. Without a volume, all user comments and data will be lost upon service restart. Configuration is primarily handled via environment variables, including a crucial SECRET for security and an ADMIN_PASSWD for moderation access. The deployment automatically utilizes Railway’s public domain for the REMARK_URL, simplifying the initial setup.

Common Use Cases

Static Blogs: Easily add dynamic comment sections to static site generators like Hugo, Jekyll, or Gatsby.
Privacy-First Communities: Replace tracking-heavy platforms like Disqus to ensure maximum user privacy and control over data.
Documentation Sites: Implement feedback loops, allowing users to leave questions or comments directly on technical documentation pages.

Dependencies for Remark42 Hosting

Persistent Volume: Required to ensure comment data persistence (mapped to /srv/var).
SMTP Server (Optional): Needed for user and administrator email notifications.

Deployment Dependencies

Implementation Details

Your template uses the following essential environment variables:

SECRET: A long, random string used for JWT signing and security.
REMARK_URL: Automatically set using Railway's public domain: https://${{RAILWAY_PUBLIC_DOMAIN}}.
ADMIN_PASSWD: Required to log in to the administrator panel for moderation.

For advanced configuration, including setting up OAuth providers or customizing limits, you can adjust variables based on the Complete parameters list found in the official documentation.
