About
Lambda Island creates and maintains several popular Clojure libraries and tools: Kaocha, deep-diff, uri, Glögi, metabase-datomic, ansi, hillchart. We also maintain some of the community infrastructure, namely the ClojureVerse forum, and the clojurians-log slack log.
You can read all about this Collective and how we plan to use in our announcement post.
