One of the key goals of CDI was to significantly improve Java EE platform extensibility at the core component level. Generic dependency injection alone goes a long way in making it fairly easy to integrate third-party components and libraries. CDI goes much farther by offering an entire portable extension API geared specifically towards writing CDI plugins. The most obvious manifestation of a resulting CDI ecosystem is plug-in collection projects like Seam 3 and it's successor DeltaSpike. However, there is actually a lot more to the CDI ecosystem, most notably tools (think IDEs) and larger projects that offer CDI pluggability.
So far there has not been a concerted effort to create a directory of sorts for the CDI ecosystem. While such a directory will (hopefully) never be completely all-encompassing it is helpful to have one place you could go to in order to find out all the plugins available for CDI. Most recently the CDI specification site added an ecosystem section to try and address this need. The page is looking pretty good already including listings like DeltaSpike, VRaptor, Vaadin, Camel, Forge and Arquillian - you should check it out. I can already see a few missing though like MyBatis/CDI, Agorava, Struts 2/CDI, Wicket/CDI, ZK/CDI and a few more (I'll reach out to the CDI folks to see why these might be missing). If you similarly see any CDI plugins that should be listed, you should try and reach out (the top of the CDI ecosystem page says how you can do so).
