OpenRPC Playground

Dependabot Status


This is a tool for editing, validating and previewing OpenRPC documents.

What is it?

This is meant to be an all-in-one developer portal for OpenRPC documents. It includes an editor and a live-preview of the documentation.

This helps developers visualize the OpenRPC and iterate very quickly on creating OpenRPC documents via the built in editor tooling.


Navigate to and start playing around. You can build your own OpenRPC document, validate existing documents quickly, or use the examples.


  • CTRL + SPACE - auto complete (TAB or ENTER to complete)
  • CTRL + N/CTRL + P - down/up a line (also works as up/down in autocomplete)
  • ALT + SHIFT + F - format document
  • CMD + K + BACKSPACE - reset to empty schema
  • CMD + K + I - pop up tooltip under cursor
  • CMD + K + V - toggle vim mode
  • CMD + K + R - replace meta schema

Configuration via Query String Parameters

The query string parameters can be used to configure the playground in different ways.


uiSchema is used for UI layer configuration. here is its interface:



schemaUrl - fetch schema by URL and display it as the content of the playground on startup.


schema - JSON String used to display it as the content of the playground on startup.


  • set splitView to false
  • hide appbar input bar
  • hide appbar examples dropdown
  • provide custom name and logo
  •[appBar][ui:title]=My Site&uiSchema[appBar][ui:logoUrl]=

Pro tip

If you want to use the content of a Github Gist with the playground, you can:

  • use the latest revision for a Gist file[gist username]/[gist ID]/raw/[file name]
  • use a specific revision for a Gist file:[gist username]/[gist ID]/raw/[gist commit ID]/[file name]
