Do you have 1:1 screenshots available? Being able to generate a website screenshot for specific OS/browser on demand might be a far better niche than trying to compete in a thumbnail segment (even if you will deliver a better service, there's a SEO battle to consider - make sure you know how to win it).
Seems fast and does a good job, but doesn't appear to support https sites?
You are right, I just noticed that too.
After the traffic slows I'll add https support thanks for the heads up! 104 concurrent users right now.
Great concept, but people are taking advantage of the fact that you're showing the latest screen shot on the right hand side of the page. It's pretty grotesque. You may want to fix that.
