Other types of software distribution, taking the suffix "-ware" have followed shareware's lead. They usually do not require the user to make a specific payment to the author. Examples include:
- Postcardware, which requires the user to send a postcard to someone
- Careware, which requires the user to donate to a charity
Another type of shareware software distribution very popular in the mobile domain are app store markets (e.g., see List of mobile software distribution platforms). There, users can often obtain applications that are free and advert banner supported, and often a paid version with no ads and maybe more features.
