Up and running in minutes

Three steps. No backend to set up, no SDK to learn.

1

Install the widget

Paste one script tag into your website. That's the entire installation — no build step, no npm package, no config file.

<script src="...widget.min.js ?key=YOUR_API_KEY" async defer></script>
2

Visitors start chatting

The widget appears in the corner of your site. Visitors click it and start talking — no account, no sign-up, no friction.

3

Your team replies in Slack

Each visitor conversation becomes its own Slack thread. Reply in the thread — the visitor sees it instantly on your site.

Built the right way

Live chat for Slack, built with no shortcuts and no compromises.

Thread per visitor

Every visitor gets their own Slack thread. Conversations stay organised and attributed — never mixed up in a single channel.

Real-time WebSocket

Messages appear instantly in both directions. No polling, no page refresh, no perceptible delay between Slack and the widget.

Shadow DOM isolated

The widget runs inside a Shadow DOM — it physically cannot conflict with your page's CSS or JavaScript. Zero style bleed, ever.

Session persistence

Visitors can refresh the page or temporarily disconnect — they automatically rejoin the same Slack thread. Conversations are never lost.

Multi-site ready

One account supports unlimited websites. Each site gets its own API key, Slack channel, and widget appearance — all from one dashboard.

Zero dependencies

The widget is a single self-contained JS file — no frameworks, no CDN calls, no npm. It loads fast and works everywhere.
