jMockups is an HTML5-based web app that lets you create and share high fidelity website mockups. A lot of folks use Photoshop to do this, but Photoshop is hard to use, lacks common HTML elements, and makes it non-trivial to share your designs and get feedback. Long term I want jMockups to be not just a tool for designing your site, but a tool that helps you design it well (including built in grid systems, an extensive widget library, etc). This is my fourth web app, the other three being Domain Pigeon (launched Jan 09 [1]), HNTrends (launched Sept 09 [2]), and Preceden (launched Jan 10 [3]). Being a developer more than a designer, I spent an endless amount of time designing each of them, which is one of the major reasons I created jMockups. Check it out and let me know how I can make it better--it's something that I hope you can all use with your sites as well.
