Note: All official clients use the integrated issue tracker on GitHub for bug reporting.

In addition to the official clients, Basho provides some unofficial client libraries, listed below. There are also many client libraries and related community projects.

Community Libraries

The Riak Community is developing at a break-neck pace, and the number of community-contributed libraries and drivers is growing right along side it. Here is a list of projects that may suit your programming needs or curiosities. If you know of something that needs to be added or are developing something that you wish to see added to this list, please fork the Riak Docs repo on GitHub and send us a pull request.

Note on community-produced libraries
All of these projects and libraries are at various stages of completeness and may not suit your application's needs based on their level of maturity and activity.
