This page is an informative section of the hCard specification.
The following implementations have been developed which either generate or parse hCards. If you have an hCard implementation, feel free to add it to the top of this list.
- Wordpress hCard Creator - I've made this simple plugin for wordpress. It adds the hCard Options submenu at Options menu, where you can create a simple hCard and put it on your blog using < ?php hcard_creator() ?> to show it. Also, it is possible to show an "export to vCard" link, which uses Brian Suda X2V. (Got send an e-mail to him regarding this)
- Wikidentity - Wikidentity is a Flash client that shows you any hCards in a page you are browsing, and allows you to search for hCards that other users have helped index. You can also export hCards that you've discovered to use in a variety of applications, such as Address Book.
- Yedda - Yedda provides hcard based identities on all of the people's profiles
- Alexa hcard search
- Microformats Bookmarklet is a bookmarklet designed for Safari (works in Firefox and Camino) that overlays on the current page to allow users to import individual hCards or hCalendars. Written by Remy Sharp.
- vCardExplorer 0.2 is a Mac OS X Application, that displays VCF-Files and extracts hCards from Websites written by Daniel Kagemann.
- Extract Microformats is a script for NetNewsWire that supports extracting hCard and hCalendar data in blog posts (via technorati service). Written by Chris Casciano
- hKit is an open source PHP 5 parsing library with support for hCard.
- Technorati Microformats Search indexes hCard, hCalendar, and hReview as announced by Tantek.
- list of pages with indexing Issues so they can be looked into as to why data is not being extracted
- Dreamweaver Extension suite from the Web Standards Project enables the authoring of hCards from within Dreamweaver 8.
- Scooch is a slide show and presentation creator that generates a hCard 1.0 for individual slide show authors and comment authors with a CSS button to parse and download via X2V. Also uses hReview 0.4 (in progress) for slide ratings and rel="tag" for categories.
- Flocktails - port of Tails extension for Flock 0.5.12 that looks for hCards, hCalendar, xFolk and hReview and tosses them into a handy topbar
- uformats is a ruby library that can parse hCalendar 1.0, hCard 1.0, hReview 0.4 (in progress) and rel="tag"
- Tails is a Firefox Extension that will display the presence and details of microformats (hCard, hCalendar, hReview, xFolk) on a webpage. Tails Export is an extended version.
- Smartzilla is a Firefox Extension that finds hCards on web pages and lets you add them to your addressbook.
- pnh_mf is a plugin for Textpattern that supports embedding hCard and other microformats in templates and blog posts. Written by Chris Casciano.
- There is evidence of built-in hCard support in the Konqueror browser. Specifically, Konqueror 3.5, in KDE 3.5 (kubuntu Breezy w/ update).
- There is evidence of a kwiki plugin for hCards. Update: the hCard kwiki plugin svn repository. See the documentation of the hCard kwiki plugin.
- X2V is a bookmarklet that parses hCard and produces a .vcf (vCard) stream. Note: needs to be updated as the spec is refined
- Duncan Walker has built a Firefox extension that gets hCard data from a webpage, uses Brian Suda's XSL (locally) to transform it to vcard format and opens the resulting .vcf file.
- George has written a Greasemonkey user script that detects hCards and allows users to easily add them to their address book application. Relies on the X2V web service to do the conversion.
- Martin Rehfeld has updated the work of David Janes and produced a greasemonkey script that finds many microformat elements, including hCards, and provides a popup menu of actions. The hCard to vCard conversion is done internally within the script. This will work with FireFox 1.5+/GreaseMonkey 0.6.4+ now.
- Mark Pilgrim has also written an hCard parser Greasemonkey user script. It is self-contained and does not rely on the X2V web service.
- Oliver Brown has written an "extension" to SimpleXML that gives simple access to hCard information in PHP 5.
- Andrew D. Hume has built a system (Wordpress plugin?) for using hCards in your blog to represent people leaving comments on blog posts.
- The hCard creator is a very simple, yet illustrative, open source user interface / form / script which creates an hCard in real-time as you type in a set of contact information.

- Microformat Base is an open-source PHP microformat aggregation crawler, currently recognizing hReview, hCalendar, and hCard.
