I was worried about my website being slow to render today (because of some scripts I wrote) so I started searching online for some sites that would show me how long it took to fetch and execute all my content on each page. I found a very nice tool over at PingDom. It will break down all the includes you use and tell you how long it took to start and finish the fetch. Pretty useful. I also came across this one as well: Browser Shots. It will render your page in 70+ different browsers and give you snapshots of them all. A great tool for people who are developing their website from scratch and are worried about cross browser compatibility!
