Running shows worldwide
Ontime worked easily out-of-the-box and grew with us as we built deep integrations within our studio.
Most importantly, our team (including the talent) love how easy it is to use.
First I used Ontime only for stage timers, but it quickly became the organizational heartbeat for many shows - big and small.
Throughout the festival season, Ontime has proven itself to be an indispensable tool for show timing.
It has transformed the way that we manage festival production reducing stage management workload, ensuring everyone is on the same page both on and off stage.
Our receiving venue uses Ontime to display the day's schedule information to guests, talent and technicians.
At show time, Ontime has been fundamental for sharing information between FOH and backstage and is, at this point, a core part of our workflow.
Keep productions in sync
Multiple surfaces, one source of truth. Keep operators and display endpoints synchronized with consistent event data.
Built for live production
Plan and run your show with a clear schedule, real-time timing, and shared event data across departments.
Ontime helps teams stay aligned while planning, rehearsing, and running live events.
Run locally, self-host, or use Ontime Cloud
Use Ontime on Windows, macOS, Linux, Docker, or a managed cloud stage. Projects stay portable, so you can choose the setup that matches the show.
See setup optionsShare the right view with every team
Send timers, backstage schedules, public signage, and operator views to any browser. Save URL presets for fixed screens and redirect connected clients remotely.
Manage remote clientsKeep delays visible during the show
Track runtime changes against the schedule and communicate the impact to production teams in real time, without rebuilding the rundown mid-show.
Understand delaysIntegrate with production systems
Use OSC, HTTP, WebSocket APIs, and the Companion module to connect Ontime with show-control surfaces, media servers, graphics, and operator workflows.

Trigger internal actions or outbound HTTP/OSC messages as cues change. Ontime also ships an MCP server for creating, editing, and auditing rundowns.

Upload your own HTML views, keep several rundowns in one project, and edit one rundown while another is live.
Create custom views
Communicate time
to presenters, artists, team members, stage managers and everyone elseThe timer sits at the core of Ontime. It shows the running timer along with information on upcoming events.
Different layouts get you started but can be customized and saved to presets while keeping responsiveness on all devices.

Communicate data
to guests and production teamsOntime distinguishes rundown as being public or production / backstage events.
This allows for having different layouts of data shown in public and backstage signage. Backstage screens also receive extra information, such as real-time information on delay scheduling.

For running shows and rehearsals
with operators, show callers and everyone involvedOntime helps operators stay on track during shows and rehearsals.
With both cuesheets and automated operator screens, your team will always be on the right cue. Team members can add their own notes to the rundown and easily customise the views to focus on the data that is relevant to them.

Manage your rundown
stay in the driver's seat and keep track of every cue, note and event propertyThe editor lets you create, delete, rearrange, and set up the information Ontime uses. Start by importing a rundown from Excel or Google Sheets, then adapt it for the show.
