Is Kidizen Still Around?
We can’t find it anywhere active. Searching both the App Store and Google Play for “Kidizen” turns up nothing from the company — the app has been delisted from both — and the marketplace’s own referral subdomain no longer resolves at all. The main kidizen.com domain technically loads, but only as a generic parked-domain page, not the marketplace. That’s three independent signs pointing the same direction, so we’re treating the app as discontinued even without an official shutdown announcement.
Kidizen’s pitch, back when it was running, was a simple one: kids outgrow clothes constantly, so buy gently-used instead of new, and resell what you no longer need instead of tossing it. New users got $5 in credit with an invite code, and sellers could earn a cut when they referred other sellers.
ThredUp is a large online resale marketplace that carries kids’ clothing alongside adult sizes — not a kids-only app like Kidizen was, but it covers the same basic use case (buy secondhand, sell what you don’t need) and it’s a link we actively track and can verify is working right now.

Frequently Asked Questions
Does the Kidizen invite code WONDER still work?
We can’t verify that it does. The Kidizen app is delisted from both the App Store and Google Play, and its site is now just a parked domain page, so there’s no live app for the code to work in.
What happened to Kidizen?
We don’t have an official announcement — no press release or company statement turned up in our check. What we do have is the app missing from both major app stores and the site reduced to a parked-domain page, which together are strong signs the marketplace has shut down.
What’s a good alternative for buying or selling kids’ clothes secondhand?
ThredUp, linked above, is a resale marketplace we currently track that carries kids’ sizes alongside adult clothing. Poshmark and Mercari are two other general resale marketplaces worth a look if ThredUp doesn’t have what you’re after.
When was this checked?
We checked Kidizen’s app listings and site in July 2026. If it relaunches, let us know and we’ll update this page.
