Documentation | Latest releases | Get support

Getting even the simplest Java logging working can be maddeningly complex, and it often gets worse at scale as your needs become more sophisticated.

Timbre offers an all Clojure/Script alternative that's fast, deeply flexible, easy to configure with pure Clojure data, and that just works out the box.

Supports optional interop with tools.logging and log4j/logback/slf4j.

While I will continue to support Timbre as always, I'd recommend new users see Telemere instead - which is essentially a modern rewrite of Timbre.

There's zero pressure for existing users of Timbre to migrate, though there are significant benefits - and migration is often quick and easy. See here for why I made the decision to release a new library.
