GuardianKit

The affordable license key system for your
Mac OS X, OPENSTEP, and NEXTSTEP applications.



GK Logo Welcome to the GuardianKit!  The GuardianKit gives Mac OS X and OPENSTEP developers what they need to quickly add licensing capabilities to their applications. The kit includes SampleApp, an application that demonstrates how to make use of the GuardianKit, and Licenser, a license key generation app. The kit comes with full developer documentation.

The GuardianKit enables you to release your application as "demoware". That is, you distribute your application on free CD-ROMs, submit it to public ftp servers, or let users download it from your website for free. The version you distribute is the "real", full-fledged one, but you distribute it with a license key pre-installed which disables some important functionality of your application. Like printing and saving, for instance. This way, users can first try your application to their liking, and then decide whether to buy a license key from you. In addition, you can send out time-limited test license keys which will fully enable your application, but only for two weeks or a month or whatever. Afterwards, your application will automatically fall back to demo mode again.


Highlights

Upto 6 different application modules (i.e. layers of functionality, like Print & Save, Import of Images, etc...) can be licensed independently. No need to release separate "Light", "Pro", and "DeLuxe" versions of your application. Instead, you can release one single version of your app, and sell "Light", "Pro", and "DeLuxe" license keys.
Upto 3 different expiration dates can be assigned to each of the 6 modules. You can release your app with a time bomb built-in, for example to ensure that a public beta version of yours will be rendered useless after, say, two months from now. Or in case a user insists on trying your application fully enabled before buying a license, you can send that user a time-limited test key, which will enable your app for, say, 30 days. Afterwards, your application will automatically fall back to demo mode.
Built-in key version numbers let you decide which users can upgrade for free. Example: users who had purchased a license key for version 2.0 can reuse their keys for your newest version 2.1, while users who had purchased a license key for older 1.x versions cannot. (To those, you will gladly offer update keys for a reasonable update fee.)
Auxiliary key infos let you enhance the GuardianKit's functionality w/o having to take a look under the core engine's hood.
All this--and more!--for just US$399.00. Great for small developers!

jpg Img A user wants a time-limited test key for your application. You launch the Licenser application, create a key that will expire at end of March, and send the key via email.
jpg Img The user launches your application and opens the License Panel. The License Panel says that your app currently runs in demo mode. The user clicks "Re-license Application". This opens the Registration Panel.
jpg Img In the Registration Panel, the user pastes the test license key copied from your email, enters a name, and clicks "Register Application". This closes the Registration Panel and opens the License Panel again.
jpg Img The License Panel now says that the demo restrictions have been turned off, but only until end of March. On April 1, your application will automatically fall back to demo mode. The user clicks "OK" to close the License Panel, and starts enjoying your now fully enabled application.
