Score: 6.5/10 (Innovation: 5, Technical: 7, Documentation: 8, Utility: 6)

Garrul is a self-hosted comments system that runs entirely on a single Cloudflare Worker using D1, KV, and Turnstile, eliminating the need for a container, VPS, or database server. It offers threaded markdown comments, OAuth sign-in, anti-spam heuristics, email notifications, an embeddable Shadow DOM widget, and importers for Disqus/Remark42/Comentario. The project is notable for packaging a surprisingly full-featured comment platform into a serverless edge deployment with genuinely thorough documentation.

Target audience: static site owners, bloggers, backend developers, devops
