Rust webserver for comments, that you can easily embed in a website.

Early development, not safe for production yet (see milestones)


  • List and post comments by topic (e.g. each article in your blog is a topic)
  • Admin approval
  • Admin notification on new comment via Matrix
  • Embedded one-file webserver
  • Customizable Tera templates
  • Comment frequency limit per IP
  • i18n
  • Petnames! (anonymous comment authors get a funny random name)
  • Designed for privacy and moderation


webcomment init

# This adds an admin password to the config (password are hashed)
webcomment psw

# edit ~/.config/webcomment/config.toml

webcomment start

Each topic is accessible at /t/<topic_name>.

Admin login is accessible at /admin. Once authenticated, you can see the pending comments on the topic pages.


If enabled, a message can be sent to a Matrix room (private or public) on every new comment.

The account must have joined the room for Webcomment to be able to send messages to it.


New comments are not public before being approved by the administrator (by default).


Uses no cookie, no unique user identifier. At each mutation (i.e. new comment or edition), the client IP address is stored for a limited duration (configurable) only for antispam to work. (antispam can be disabled) The client IP address is also stored for each pending comment, but it is removed as soon as the comment gets approved.

However, keep in mind that if a reverse proxy (or any other intermediate tool) is used, IP addresses and other metadata may be logged somewhere.
