I am very excited to announce the release of Marcato. Marcato allows you to create site-specific browsers on your iPhone. Marcato maintains separate cookies, local storage, and cache for each browser. The browsers live within the Marcato app.
I created Marcato because I wanted a way to isolate my web browsing activity for certain sites. I use Facebook, but I prefer not to run the Facebook iPhone app and I prefer not to have my other web browsing activity tied to my Facebook account. I also try to avoid logging in to sensitive accounts from my primary browser, in order to avoid any potential cross-site request forgery attacks. I have been using Fluid on the Mac for years, and I wanted something similar for iOS.
You can buy Marcato in the App Store now for $4.99 (USD). If you would like to learn more about the app, please visit its product page and check out this video.
