lightweight Disqus alternative

Project description

Isso – a commenting server similar to Disqus

Isso – Ich schrei sonst – is a lightweight commenting server written in Python and JavaScript. It aims to be a drop-in replacement for Disqus.


  • Comments written in Markdown
    Users can edit or delete own comments (within 15 minutes by default). Comments in moderation queue are not publicly visible before activation.
  • SQLite backend
    Because comments are not Big Data.
  • Disqus & WordPress Import
    You can migrate your Disqus/WordPress comments without any hassle.
  • Configurable JS client
    Embed a single JS file, 65kB (20kB gzipped) and you are done.
