An oEmbed consumer library written in Ruby, letting you easily get embeddable HTML representations of supported web pages, based on their URLs. See for more about the protocol.


gem install ruby-oembed

Get Started


Get information about a URL via an OEmbed::Provider. This library comes with many Providers built right in, to make your life easy.

resource = OEmbed::Providers::Youtube.get("") #=> true
resource.thumbnail_url #=> ""
resource.html #=> <<-HTML
  <object width="425" height="344">
    <param name="movie" value=""></param>
    <param name="allowFullScreen" value="true"></param>
    <param name="allowscriptaccess" value="always"></param>
    <embed src="" type="application/x-shockwave-flash" width="425" height="344" allowscriptaccess="always" allowfullscreen="true"></embed>

If you'd like to use a provider that isn't included in the library, it's easy to create one. Just provide the oEmbed API endpoint and URL scheme(s).

my_provider ="{format}")
my_provider << "http://**"
my_provider << "http://**"
resource = my_provider.get("") #=> OEmbed::Response #=> "My Cool Service"

To use multiple Providers at once, simply register them.

OEmbed::Providers.register(OEmbed::Providers::Youtube, my_provider)
resource = OEmbed::Providers.get("") #=> OEmbed::Response
resource.type #=> "video" #=> "Youtube"

Last but not least, ruby-oembed supports both oohEmbed and Embedly. These services are provider aggregators. Each supports a wide array of websites ranging from to xkcd.


This library works wonderfully on its own, but can get a speed boost by using 3rd party libraries to parse oEmbed data. To use a 3rd party Formatter, just be sure to require the library before ruby-oembed.

require 'json'
require 'xmlsimple'
require 'oembed'

OEmbed::Formatter::JSON.backend #=> OEmbed::Formatter::JSON::Backends::JSONGem
OEmbed::Formatter::XML.backend  #=> OEmbed::Formatter::XML::Backends::XmlSimple

The following, optional, backends are currently supported:
