Real-time messaging
Messages land instantly over live sockets, with typing indicators and read ticks.
WhatChat drops a familiar green-and-white chat bubble onto your website. Visitors start chatting instantly — no app, no sign-up — and your team replies in real time.
Built to feel instantly familiar to your customers, and simple for your team.
Messages land instantly over live sockets, with typing indicators and read ticks.
Visitors can send screenshots and documents right from the chat window.
A full emoji keyboard, so conversations feel human — not like a ticket form.
Returning visitors pick up right where they left off, even after a refresh.
Opens full-screen on phones, and as a tidy floating panel on desktop.
Rendered in an isolated Shadow DOM, so it never clashes with your site's CSS.
No build tools, no plugins. Just paste and publish.
Sign up on WhatChat and grab your company, website and widget IDs.
Add the script tag just before </body> on any page.
The green bubble appears bottom-right. Reply from your WhatChat inbox.

No. WhatChat only looks and feels like WhatsApp — it runs entirely in the browser on your site.
The script loads after your page is interactive, so it won't block rendering.
Yes. Anywhere you can paste a script tag, WhatChat works.
Look at the bottom-right corner — that's the live WhatChat widget. Click it to say hi!
