A self-update framework for Cocoa developers that is both free and user-friendly software.
If you are looking for more advanced features like tar, DMG disk images, bz2, gz, or gzi archives, Sparkle may be a better option for you. However, Submarine is a great choice for those who just need simple, hassle-free updates.
One of the best things about Submarine is that it's completely free for any use - whether you're using it for open source or commercial purposes. The one condition is that you must include a visible link to Deep IT in your product.
Overall, if you're looking for a reliable, easy-to-use software update tool, Submarine is definitely worth checking out. It's simple, efficient, and best of all - it won't cost you a dime.
