ZAC Browser

2008 - 2026
dead us
john lesieur wrote it for one child. his grandson zack was diagnosed with autism at three and could get nowhere with an ordinary browser, so lesieur, who ran a small software company called people cd, took the kids' program he already sold and stripped it down to a handful of controls with an aquarium on the front page. no address bar, and a short list of places the child was allowed to go. he put it online free in 2008 and left it up for eighteen years. it shut down on 2 april 2026, and the homepage is now a file with nothing in it.

~ the obituary ~

Zack was three when he was diagnosed with autism, and computers frustrated him the way most things designed for everyone frustrate someone who is not everyone. His grandfather happened to own a software company. John LeSieur ran People CD Inc. and had already shipped a children's program called KidCD in 2006, which turned out to work for Zack: he could use it on his own, without a hand on the mouse.

KidCD 2.0 arrived in 2008 with a feature that rotated the icons on screen automatically. For most children that is novelty. For an autistic child who depends on the layout staying where it was, it broke everything. So LeSieur built a second version with the icons nailed down and an aquarium on the front page, and in 2008 he released it as ZAC Browser, Zone for Autistic Children. It ran on Windows going back to 98, it asked for 256 megabytes of RAM, and it cost nothing.

Eighteen years later it went away. The shutdown date is 2 April 2026, and the farewell notice on zacbrowser.com thanked more than seven and a half million users before it too was taken down. The domain still answers today. The response is zero bytes long, last modified 16 April 2026.

~ what it removed on purpose ~

Every other kids' browser of that era was a filter with a cartoon on it. ZAC was a subtraction. There was no address bar, because typing a URL was not a task the child was being asked to perform. Most of the browser chrome was gone, along with most of the web. What remained was a small set of destinations that had been chosen in advance, PBS Kids and Sesame Street among them, reachable by pressing a picture that stayed in the same place every single time.

That last clause is the design. Predictability was the feature, and the way you build predictability is by deleting things until nothing can surprise you. Accessibility software has spent the eighteen years since ZAC shipped learning the same lesson slowly and at much greater expense.

~ eighteen years of a free download ~

ZAC Browser got a run of press in 2008 and 2009 that small software almost never gets. PCWorld reviewed it and the download sites carried it, but the thing that kept it alive was autism parent blogs passing it hand to hand, which they went on doing for years after the last release, version Gold on 10 June 2009.

Then it just sat there. Nobody ever put a subscription on it and nobody bought it, and no update shipped for roughly seventeen years. A Windows executable from 2009 kept working well enough for people to keep recommending it, and the download link stayed up on a domain someone kept paying for. That is a strange kind of longevity and it is entirely a function of one person deciding not to take it down.

~ why it is here ~

This one is American and it is small and it never had anything to do with me. I am writing it because the shape of it is unusual on a site full of companies that died of funding. ZAC Browser had no investors to disappoint and no market to lose. It ended because the man who maintained it stopped, which is the way almost everything on the early web was supposed to end and almost nothing did.

a rose fades by morning. a wreath stays on this grave for good, with your name on it.

from $1, paid once through stripe. it keeps the graveyard running: the hosting and the nightly digging. adopt it and the headstone reads "maintained in memory by" you. the groundskeeper plants new wreaths at the next tending, usually within a day.
