WebCallHub puts a call button on your website. Visitors click it and talk to your team live in the browser — no phone number, no app, no download on their side. You paste one line of code, or install the WordPress, Shopify, Wix or Chrome add-on. Calls run peer-to-peer over WebRTC and are encrypted end to end. Free forever: 1 seat, 1 website, 200 minutes/month, no credit card. Paid plans from $19/mo add unlimited browser minutes, more seats, analytics, and phone fallback when nobody is online.
