<h1>Onionoo</h1>
<p>Onionoo is a web-based protocol to learn about currently running
Tor relays and bridges. Onionoo itself was not designed as a service
for human beings—at least not directly. Onionoo provides the
data for other applications and websites which in turn present Tor
network status information to humans. There are currently two
Onionoo clients available:</p>
<ul>
<li><a href="https://atlas.torproject.org/">Atlas</a> is a web
application to discover Tor relays and bridges. It provides useful
information on how relays are configured along with graphics about
their past.</li>
<li><a href="https://code.google.com/p/moniono/">mOnionO</a> is an
Android app that lets you add your relays or bridges to your favorites
list and keeps you always informed whether they are running or
not.</li>
</ul>
<h2>Developing Onionoo applications</h2>
<p>The project pages of the Onionoo clients listed above have further
information for contacting the authors and contributing ideas or code.
The authors will be happy to hear your thoughts!</p>
<p>You don't find your favorite Onionoo client above? Want to
implement your own and tell us to add it to the list? The Onionoo
clients above are backed by a web-based
<a href="http://onionoo.torproject.org/">protocol</a>, which
facilitates developing new applications displaying Tor status
information. Here are a few ideas for new Onionoo clients:</p>
<ul>
<li>Tor controller extension: Extend
<a href="<page projects/vidalia>">Vidalia</a> and/or
<a href="<page projects/arm>">arm</a> to look up details for the bridge
that the user is running and display what pool the bridge is contained
in.</li>
<li>Social network site plugin: Add a plugin to the social network
site of your choice to show your friends what Tor relays and bridges
