Replyo is a self-hosted comment system for static and PHP websites. It stores comments as flat JSON files on your own hosting, so there is no database to set up and nothing loaded from a third-party service.

Add a comment section to any page by pasting two lines of code. The page can be plain HTML, PHP, or built with a static site generator like Astro, Jekyll or 11ty. Each page keeps its own separate comment thread.

Comments are managed from a simple admin dashboard where you can approve, delete and moderate. New comments can be held for approval before they appear, and a built-in honeypot quietly blocks spam bots.

Everything runs on standard shared hosting with PHP 7.4 or newer. No framework, no Composer, no build step. Upload the files, run the installer once, and you are ready.
