chillax is a CouchDB abstraction layer for Common Lisp licensed under the MIT license. The original author of chillax is Josh Marchán; Ian McEwen subsequently worked/is working on CLOS bindings, since the original version was written for Sheeple.
chillax also includes a CouchDB view server, which can be made with make-chillax-server.lisp. Currently-supported by make-chillax-server.lisp are sbcl and ccl.
Note that, at least on some systems, versions of YASON prior to commit 00b9a5c06b7c4113a48518a1f136637efb4458b9 will not work (in this commit, #\Return was added to the list of whitespace characters recognized). Using these versions instead of 0.1 is recommended anyway for performance reasons.
