Playground

Validate an OPF deck in your browser.

Edit the JSON on the left and the canonical validator re-runs as you type — schema errors, advisory catalog warnings, and all. Start from an example deck or paste your own.

Load example

deck.opf.json

{
  "name": "Minimal OPF Deck",
  "slides": [
    {
      "title": "Minimal OPF Deck"
    },
    {
      "title": "What This Shows",
      "items": [
        "A title slide",
        "A simple list slide",
        "A closing slide"
      ]
    },
    {
      "title": "Next Steps",
      "text": "Use this as a small valid OPF starting point."
    }
  ]
}

Loading the validator…

Validation runs entirely in your browser using validatePresentation from @openpresentation/opf v0.7.0 — the same call your pipeline makes. Nothing you paste here is uploaded anywhere.
