This will be commercial, similar to PyCharm, RubyMine and the other JetBrains IDEs. I'm considering a slightly restricted free edition that can't be used for commercial work, but I haven't worked out the details yet. It almost certainly won't be fully open source, but I'm considering having a small closed source core and then the majority of the Clojure implementation being open source and extensible. This will need some thought and probably won't happen right away though. In the short term it'll be closed source commercial.

Yeah, I would definitely appreciate a free edition to try out. It would have to be pretty impressive to switch me away from emacs (and vim), and I'd have to try it first to know.

how does that work if it's a fork of la clojure? are you paying intellij? did they licence their code under a very open licence?

[lemming]

Yes, they released their code under the Apache license. I checked with them before deciding to go ahead with this and they didn't have a problem with the idea.
