Ontime is a browser-based application for managing event rundowns, scheduling, cueing, and live show timing. It is built for real-time collaboration across production roles and for reliable operation in live environments.

Key Features

  • Rundown editor to create, reorder, and manage cues, notes, and event properties
  • Live timer views with customizable layouts and saved presets for different screens
  • Role-oriented operator and signage views for directors, backstage, and public displays
  • Real-time delay workflows to track runtime changes and communicate updates to the team
  • Automation and control via operator control or system clock-driven automated rundowns
  • Integrations via OSC, HTTP, and WebSocket APIs, plus a Companion module for show-control workflows
  • Import support for rundowns from spreadsheets (e.g., Excel or Google Sheets)

Use Cases

  • Stage management for conferences, festivals, and touring productions with shared timing and cues
  • Broadcast and streaming productions needing synchronized rundown and operator views
  • Venue signage for public schedules and backstage operational displays

Limitations and Considerations

  • Ontime Cloud does not currently support OSC automation; self-hosted deployments can use OSC.

Ontime is well-suited to productions that need a central, shared source of truth for scheduling and show timing. Its multi-view approach and integration options make it practical for both small teams and complex live workflows.
