Pre-built, fully customizable chat UIs

Launch a professional, responsive chat interface out of the box. Pre-built components are designed for flexibility, so you can match your brand and user experience without building from zero.

Inbox

The Inbox UI is a complete messaging hub for your web app. It displays a conversation list on the left and the selected chat on the right—just like email or Slack. Ideal for apps where messaging is a core feature, the Inbox is perfect for use as a full-page chat system or message center.

Great for: marketplaces, dashboards, internal tools

Chatbox

The Chatbox UI is a compact chat component designed to fit into any part of your web app layout. Show a conversation next to an order, profile, or booking to keep messaging contextually relevant. An embedded chat UI gets you real-time messaging without taking over the whole screen.

Great for: user profiles, booking systems

Popup

The Popup UI adds a floating chat window to your site that users can open on demand. It's lightweight, intuitive, and appears in the bottom-right corner by default—just like the live chat widgets users already know. A website chat integration that doesn't disrupt your layout.

Great for: lead generation, customer support chat
