(Note I added this section because I didn't see it fitting logically in any other section on this page, feel free to move about.)
- Prasi implements OpenID authentication from version 1.3 onwards. The users still need to login once using a (afterwards discardable) username/password, then enable an OpenID credential in their profile (which they then can use to login), but this is to maintain the same level of account security as for non-OpenID users.
- Wefis version 1.5 (note: still in beta, not publically available yet) will be bundled with version 1.3 of Prasi so will automatically gain OpenID compatibility at that time. Version 1.4.2 is bundled with Prasi 1.2 so upgrading Prasi to 1.3 will also make Wefis compatible immediately.
The following demos don't necessarily implement all of the consumer functionality, but instead provide a simple example of how you might implement a consumer. (or indeed, part of one.)
- Original Demo: the original proof of concept demo, still maintained alongside developments to the consumer library. This demo does full signature verification, so it is a good simple consumer to test an ID server against. AJAX and Classic versions are provided separately so that you can ensure that your ID server works with both.
- Combo AJAX/Classic Demo:� an example of how to combine AJAX and classic modes into a single form and use whichever one is appropriate for a given user's browser. This demo doesn't support the new protocol, but that doesn't really matter since it's just an example of how to do the in-browser bit anyway.
- Mart's guestbook: A very simple consumer implemented as a CGI script. It's written in Perl and uses the Net::OpenID::Consumer module. (Simple mode only, for now.) Source code is available. This consumer operates in "dumb" (stateless) mode, so can be used to test your OpenID server for support. You don't need to actually leave a comment: if you see the comment entry form, you've authenticated successfully.
- Brent Dax's demo� is designed to show how a real site might implement OpenID in a fairly pretty way, at least in Firefox.
- sneak's demo is another stateless consumer, this time in PHP. Full source code is available. This will soon be integrated into Ichiban.
- libopkele demo is a full-blown consumer done in C++ using libopkele, which does nothing but consumes identities.
- Dave Holland's guestbook demo is another simple OpenID-based guestbook, implemented as a Perl CGI script using Net::OpenID::Consumer. The source is available.
- NetMesh's FirstSSO Demo shows serving different content to different people in PHP, Java and Perl implementations
The following libraries are available to make it easier to implement a consumer. Currently the list is very small, but we will work on that in the coming weeks.
- "PHP-OpenID" OpenID server and consumer library based on the python library. Complete, with examples. Should work on PHP >= 4.1.0 and does not require PEAR.
- "OpenLID" combines LID and OpenID into one library (extremely easy to use API). Supports DH key encryption via PHP or a Python/Perl fallback. Comes with a wrapper for profile retrieval, which however can be left out.
- OpenId for Wordpress Currently in very early beta.
- NetMesh InfoGrid LID PHP OpenID, Yadis and LID support
- OpenID extension for MediaWiki. A MediaWiki plugin that acts as a consumer and an identity provider.

- http://openid.nterface.com/ - .NET OpenID consumer library written in C#.
- http://www.openidenabled.com/openid/libraries/csharp - .NET OpenId consumer library from JanRain
