Editorial interest 81/100 Selection signal · not a rating of the site

A free Chrome and Firefox extension for customizing WhatsApp Web with themes, backgrounds, fonts, sounds, and sidebar controls.

Landing page captured for the 2026-09-02 issue.

Field notes

The extension works by layering user-selected presentation changes onto WhatsApp Web rather than replacing the messaging service itself. Its customization model includes per-chat, sidebar, and welcome-screen backgrounds, uploaded fonts assigned by message direction, replacement notification sounds, and JSON import/export for sharing or backup. The homepage lists 12 named themes and reports 800+ Chrome users plus 50+ Firefox users, while Spanish is available and Portuguese variants are described as forthcoming.
