Commentator

A commenting system for your blog or website. Comments are stored on any S3-compatible store.

I built commentator to provide an easy to use (and easy to host) free commenting system with advanced functionalities.

Features

Commentator provides:

• Multi website support: one instance of Commentator can manage comments for multiple websites.
• An easy-to-use API to manage comments and events. A public API allows users to create or retrieve approved comments, and a admin API allows you to administrate comments (approve them or delete them for example). Everytime a comment is added an event is generated into a dedicated file on S3. The API allows you to read and delete the events. You can use this file to be notified when a new comment is added.
• Rate limiting, either by IP or using the requests x-forwarded-for header.
• A "challenge" system to avoid spammers.
• An in-memory cache for comments, for performances and to avoid hitting S3 too much.
• Metrics about the applications exposed using the Prometheus format.
