I make between $500 und $100 per month off my stand-alone cross-browser testing tool:
http://www.browseemall.com
The product was launched on february this year and it's growing nicely so far. Not real recurring yet, as every sale comes with one year of free updates.
Interesting. How many unique views a month does your site get now and what kind of conversion rates are you seeing? I am planning to launch a paid version of my app, http://www.pageblox.com and my potential customers are also developers/designers.
