<p>A <a href="Userscript_manager" title="Userscript manager">userscript manager</a> is a type of browser extension and augmented browsing technology that provides a user interface to manage scripts. The main purpose of a userscript manager is to execute scripts on webpages as they are loaded. The most common operations performed by a userscript manager include downloading, creating, installing, organizing, deleting and editing scripts, as well as modifying script permissions (e.g. website exceptions).
</p>
<div class="mw-heading mw-heading2"><h2 id="Userscript_repositories">Userscript repositories</h2></div>
<p>One aspect of userscripts is that they can be shared. They can be uploaded to a userscript repository where they become available to other users for downloading.
</p><p>Historically (circa 2005–2011) userscripts.org, created by American programmer Jesse Andrews, was the largest such repository for userscripts. Over time, the site was transitioned between various maintainers before it went offline completely in May 2014.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> All that remains is a mirror, which is useful for archival purposes.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>
</p><p>A handful of the most active contributors in the userscripts.org community<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> created <i>OpenUserJS</i>,<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> which is actively in use today. Also available is <i>Greasy Fork</i>, a repository largely developed and maintained by Canadian programmer Jason Barnabe.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>
