Lightning is a minimalist web browser designed with one thing in mind - speed of search. An order of magnitude smaller than other browsers, Lightning loads in less than a second and is ready to use straight away. Enable the "Lightning Lookup" service and search on selected text from any application in an instant by typing command-@.

Based on Webkit (the already fast core of the Safari and Chrome browsers), instead of unloading browsed pages as you navigate, Lightning keeps a buffer of many WebBrowser objects in memory. This allows you to return back to a previously viewed page instantaneously without having to wait for it to reload. This optimisation makes a huge difference to speed of navigation.

URL's (starting with http://) or search items can be selected or entered into the address bar. For search terms, select the site you wish use as a search engine on the popup list at the left hand side.

Other features include:
* History and Bookmarks are HTML pages containing an (optional) snapshot of the page when it was last viewed.
* The Bookmarks page is WSYWIG editable to "arrange" them and can be used as your home page. Use the “Manage/Save Bookmarks" menu item to make your changes permanent.
* Preloads next page off-screen when you hover over a link.
* Page by Page control over Flash content and cookies.
* All the usual trackpad gestures including zoom supported.
* To close a tab or remove a bookmark tap it's icon.
* Full Spelling/Grammar checking available via edit menu.
* As a final boost to initial page load try Google DNS on or

Lightning may not be the most refined browser on the internet but from the look of the reviews it may just be the fastest! Give it a try.

True to its name

True to its name, this browser is lightning fast. (...unless you have a really slow internet connection…) It is very simplistic, with just enough to get by with, which is nice for a change. It seems as if browsers are trying to do everything at once, but not this one. Although it could use a facelift, overall I thoroughly like it. Congrats to the developers for thier hard work and great product.
EDIT: Thanks for the tip on how to get rid of the mismatch error! It works perfectly now :)
I love how it's so fast and simple, but I can not download the update (v.1.4.3) as it downloads almost all of the way, and then starts over again!! after about five times of doing this, it comes up with an error message "Hash mismatch" It's very infuriating!
Please fix as soon as possible!
Thanks a ton

Great App, needs a bit of polishing round 2


This app has definitely been improved during the last several releases. It now has key shortcuts wich help migration from safari immensely. Also, the "pretend to be chrome" function helps compatibility with websites (though "pretend to be 'firefox' or 'internet explorer'" would be helpful as well). Overall, this is a speedy little browser that I like, in many ways, better than safari, and leaps above firefox or chrome (generally because it was made for mac and is seamless with it.)

My only qualm is, though it is generally stable, there are a few quirks that need to be polished (like the odd tab bar, some crashes, etc.)

I say, use it! :D
