One of the most elegant solutions for Catalina users comes directly from the Google Chrome browser. Chrome allows you to install any website as a standalone application. This transforms the WhatsApp Web interface into a dedicated program with its own icon in your dock, separate from your other browser tabs.

One of the best improvements to WhatsApp Web is that, after initial setup, your phone does not need to stay connected to the internet for your web session to remain active. You can now link up to four companion devices to your account, and they will sync independently.

| Browser | Compatibility with WhatsApp Web | Why? | | :--- | :--- | :--- | | | ✅ Perfect | Still updated for Catalina (for now). | | Firefox | ✅ Perfect | Fully supports necessary security protocols. | | Safari | ⚠️ Spotty | Older WebKit engine may cause connection drops. | | Brave / Edge | ✅ Perfect | Built on Chromium (same engine as Chrome). |
