I would be lying if I said I have not already considered something
like this.  But it makes me smile that others have the same idea.

For those on the list who don't know me, I'm both the author of Luvit
( and work for Cloud9 (

I've recently launched a couple node learning sites (, and  While at the same time as trying to make the
developer story better for node.js developers, my evening hobby is
helping the luvit community grow.

I agree that a purely cloud-based ide as it exists today it rather
limiting.  I'm aware of the limitations and am working very hard to
make it useful for a broader range of tasks.  Some ideas include a
local version that runs offline, a way to possibly integrate with your
own vps, and some other neat ideas.  The situation is getting much

I will say that luvit isn't ready to make something at large as the
infrastructure for  Luvit (and lua) don't have a very robust
debugging system yet.  And luvit in particular is rather hard to debug
at the moment.  Expect to spend many hours with debug statements
littered throughout your code.  I'm confident this situation will
improve with time and eventually luvit will be a first class way to
write high-performance network servers using lua.

I try to not push Luvit too hard on this mailing list since it's
somewhat incompatible with stock lua, but I'll happly help with any
efforts in this area since it overlaps heavily with what I work on all
