Schnack is a simple Disqus-like drop-in commenting system written in JavaScript.

• Documentation
• Say hello to Schnack.js
• Follow @schnackjs on Twitter

Features:

• Tiny! It takes only ~8 KB!!! to embed Schnack.
• Open source and self-hosted.
• Ad-free and Tracking-free. Schnack will not disturb your users.
• It's simpy to moderate, with a minimal and slick UI to allow/reject comments or trust/block users.
• webpush protocol to notify the site owner about new comments awaiting for moderation.
• Third party providers for authentication like Github, Twitter, Google and Facebook. Users are not required to register a new account on your system and you don't need to manage a user management system.

This is not a new idea, so there are a few projects that are doing almost the same thing:

• CoralProject Talk - Node + MongoDB + Redis
• Discourse - Ruby on Rails + PostgreSQL + Redis
• Commento - Go + Node
• Isso - Python + SQLite3
• Mouthful – Go + Preact
