Ask HN: How do I build a mockup web app?

4 points by Hexarcos ↗ HN
How are services like myBalsamiq (web version of Balsamiq) built ? Is there a set of tools for this kind of drag and drop prototyping and wire-framing? Or it just rely heavily on javascript.

Having never used myBalsamiq, I'm not sure what they built it in, but some of the tools you could use:

Flash, jQuery, ExtJS, HTML5

Isn't their desktop app built in Adobe Air? or have they moved away from that? I haven't used it in a while.
