Using Ontime?

Let us know! Ontime improves from the collaboration with its users. We would like to understand how you use Ontime and appreciate your feedback.

We would also like to include a testimonials section in our ✨new website✨. It would be great to showcase the diversity of users running Ontime.


Ontime is a browser-based application that manages event rundowns, scheduling, and cueing.

With Ontime, you can plan, track your schedule, manage automation and cross-department show information all in one place.

Ontime is made by entertainment and broadcast engineers and used by

  • Conference organisers
  • Touring shows and receiving venues
  • Broadcasters and streamers
  • Theatres and opera houses
  • Houses of worship

For live environments

Ontime is designed for use in live environments.
This guides the application into being flexible and efficiently integrating into different workflows.

For teams

All information added in Ontime is shared with the production team and other software / hardware in your workflow.
Ontime also improves team collaboration with dedicated views for cuesheets and operators, and for public and production signage.

Simple infrastructure

All the data is distributed over the network, making its distribution and infrastructure flexible and cheap.
With the availability of the docker image, you can also leverage IT infrastructure to make Ontime available online for your team and clients.

Ontime is made by video engineers and entertainment technicians.

Using Ontime

Ontime can be started by downloading the latest release for your platform.
Alternatively you can also use the docker image, available at Docker Hub

Once installed and running, any device in the network has access to Ontime.

Ontime provides different screens which allow for different types of interactions with the data. These are called views.
Each view in Ontime focuses on empowering a specific role or achieving a particular task.

You can access the different views by reaching the ontime server, in your browser, at (default port 4001) http://localhost:4001 or

For the backstage views
IP.ADDRESS:4001/timer      > Presenter / Stage timer view
IP.ADDRESS:4001/minimal    > Simple timer view
IP.ADDRESS:4001/clock      > Simple clock view
IP.ADDRESS:4001/backstage  > Stage Manager / Backstage view
IP.ADDRESS:4001/countdown  > Countdown to anything
IP.ADDRESS:4001/studio     > Studio Clock
For the public views
IP.ADDRESS:4001/public     > Public / Foyer view
IP.ADDRESS:4001/lower      > Lower Thirds
For production views
IP.ADDRESS:4001/editor    > the control interface, same as the app
IP.ADDRESS:4001/cuesheet  > realtime cuesheets for collaboration
IP.ADDRESS:4001/operator  > automated views for operators

Unsigned App

When installing the app you would see warning screens from the Operating System like:

in Windows

Microsoft Defender SmartScreen prevented an unrecognised app from starting. Running this app might put your PC at risk.

or in Linux

Could Not Display "ontime-linux.AppImage

We currently only sign MacOS releases.
Purchasing the certificates for both Mac and Windows would mean a recurrent expense which we are not able to cover.

You can circumvent this by allowing the execution of the app manually.

  • In Windows: click more -> Run Anyway
  • In Linux: right-click the AppImage file: Properties -> Permissions -> Allow Executing File as a Program

If you have tips on how to improve this or would like to sponsor the code signing, please open an issue


Looking to contribute? All types of help are appreciated, from coding to testing and feature specification.
