Have all the debugging power no matter what editor/IDE you choose.
Whenever it can, FlowStorm tries hard to provide the same features for Clojure and ClojureScript.
FlowStorm is and will always be free as in speech. So no money involved and use it however you like.
Clojure as most Lisps are designed from the ground to support interactive programming, so it is FlowStorm.
Every situation requires a different strategy. From stepping, trough printing, to scope capturing and repl poking, FlowStorm tries to support all debugging strategies.
Most of the provided tools are great for chasing bugs, but FlowStorm is designed not only as a debugger but as a development sidecar to enhance your interactive programming experience.
