Ontime on Ubuntu 24.04

Overview

Ontime is an open source, self hosted application for managing the timing of live events, broadcast productions and theatre shows. An operator builds a rundown of events, each with its own duration and cues, and drives the show from a control view while a set of realtime display screens stay in sync across the network: a large stage timer for presenters, a backstage view for crew, a studio clock, a timeline and public information screens. Timers can count down, count up or roll against the clock, and the operator can start, pause, load and adjust events on the fly, add or remove time, send messages to the screens and follow the schedule as it drifts. An HTTP, WebSocket and OSC integration API lets other systems read the running state and drive playback, with companion integrations for tools such as vMix, OBS, QLab and disguise.

It suits show callers, stage managers, broadcast gallery operators and conference producers who need every screen in the room counting to the same clock, and anyone who wants precise, shared timing for a live production without a proprietary timing desk.

Common uses

• Keep every screen in a live event counting to the same clock
• Run rundowns and cues for a broadcast, theatre or conference production
• Drive show timing from other systems over the HTTP, WebSocket or OSC API
