ZAC Browser (Zone for Autistic Children) is a web browser designed specifically for children and teenagers with autism and autism spectrum disorders such as Asperger syndrome, pervasive developmental disorders (PDD) and PDD-NOS.

Because autistic children display characteristics such as impairments in social interaction, impairments in communication, restricted interests and repetitive behavior, the standard browser experience can often be overwhelming. The ZAC browser reduces the number of user interface controls and removes access to much of the Web in order to simplify the experience for autistic children.

ZAC browser is available as a free download for Windows 98/ME/2000/XP/Vista.

John LeSieur had a grandson named Zack who was diagnosed with severe autism at the age of 3. Because of the autism, the child was often very frustrated when using the computer. LeSieur owned People CD Inc., a software production company, called and released a web browser for children called KidCD in 2006. KidCD proved helpful for Zack, as he was able to use the computer on his own.
