Demo Time

Auto-proceed and looped playback

You can configure Demo Time to advance scenes automatically after a delay, and optionally loop back to the beginning of the act when it reaches the end.

This is useful when you want a demo that feels like a polished recording, while still running live so interactions, timing, and environment stay real. It is perfect for booth showcases at conferences where your demo needs to keep going without a presenter.

Scene auto-proceed

Set autoAdvanceAfter on a scene to move to the next scene after the configured delay (in seconds).

demo.json
{
  "$schema": "https://demotime.show/demo-time.schema.json",
  "version": 3,
  "scenes": [
    {
      "title": "Intro slide",
      "autoAdvanceAfter": 5,
      "moves": [
        {
          "action": "openSlide",
          "path": ".demo/slides/slide-1.md"
        }
      ]
    }
  ]
}

Act-level loop

Set loop: true at the root of the act file to restart from the first scene when the act reaches the end.

demo.json
{
  "$schema": "https://demotime.show/demo-time.schema.json",
  "version": 3,
  "loop": true,
  "scenes": [
    {
      "title": "Intro slide",
      "autoAdvanceAfter": 5,
      "moves": [
        {
          "action": "openSlide",
          "path": ".demo/slides/slide-1.md"
        }
      ]
    },
    {
      "title": "Open file",
      "autoAdvanceAfter": 5,
      "moves": [
        {
          "action": "open",
          "path": "showCase.ts"
        }
      ]
    },
    {
      "title": "The end",
      "autoAdvanceAfter": 5,
      "moves": [
        {
          "action": "close"
        },
        {
          "action": "openSlide",
          "path": ".demo/slides/slide-2.md"
        }
      ]
    }
  ]
}

Status bar automation indicator

When auto-proceed is active, Demo Time shows an automation indicator in the status bar.

  • It reflects whether automation is running or paused.
  • It shows loop status when act looping is enabled.
  • It shows a countdown while waiting to advance.
  • You can pause and resume auto-proceed directly from the indicator.
