System Requirements

Kloksi runs in the browser, on the web only. All you need is a current browser and an internet connection. There's no app to install.

Browser

Use a current version of Chrome, Edge, Firefox or Safari, on any device.

A few output controls depend on the browser, and show only where it supports them:

Every device stays connected to Kloksi for live updates. A stable connection is best, and a wired connection is worth it for a screen that matters.

A short dropout won't stop your show. See What happens when a connection drops.

Outputs keep counting while they're disconnected, and catch up when they reconnect.
Scheduled and linked timers run on the server, so they still start with the Controller closed.
The Controller shows its connection in a badge: connected, reconnecting or not connected.
Edits made while offline show as not saved, with Retry and Dismiss, and save once you're back. Leaving the page with unsaved edits asks you first.
Actions such as Play aren't queued while offline. Kloksi tells you the action wasn't sent, so a timer can't start late by surprise.

Chimes play from the device's speakers on the Controller, Viewer and Moderator. Each device can mute them, and remembers that.

Kloksi's interface is available in English and Russian. Set the language for a room in Settings ▸ Language, or for a team in its settings.
