InstantStorm: a free Flash screensaver creator

10th Anniversary

It's been 10 years since we released the first InstantStorm to the public. Big thanks goes to all users and project supporters. You're all awesome!

For more, check out the project history or our anniversary post on Facebook.


InstantStorm is a powerful freeware Flash screensaver creator that turns your Adobe Flash files (SWF) into professional screensavers in no time. Unlike other similar tools, InstantStorm is actually free of charge even for commercial use and does not add any nag screens or other annoying things to your output files. Apart from that you can customize virtually anything: the settings dialog, the installer (including all texts and images), the screensaver behavior, and more. Need to build a complex corporate screensaver, make your very own Flash screensaver for your friends and family, or just convert your favorite Flash movie to a screensaver for your own computer? InstantStorm is the right program for you!
