How we review: what "tested" means on CESXY, and what it does not

For builders

Made something small?
Let real people use it.

Send us a public project you have the right to share. An editor will use it, check the basics and write an honest note. You can also start from a wish someone else posted.

Submit a build →
  1. Wish it.Someone posts a need on the Wishes board, or you notice one in your own life.
  2. Shape it.Cut the idea down to the one action a person needs to complete.
  3. Build it.Make that action work at a public address, with AI doing as much of the work as you like.
  4. Submit it.Send it to CESXY so an editor can try it and decide whether to list it.

How labels work

Tested isn't certified.
It's a use note.

Badges are earned by testing and are never sold. Creators do not see our verdict before it is published. A label records what an editor saw on the day; it is not a guarantee.

The short version

What sits behind
A CESXY label.

Before you trust a listing, you should know who wrote it and on what terms. Here are the four facts that matter.

  1. Who tests.CESXY editors, who open each project and use it the way a normal visitor would.
  2. What we check.That the address loads and the core action works, plus login, payment, mobile use and obvious limits.
  3. What it costs.Free review and listing cost nothing; paid deep testing is a separate service and never buys a badge.
  4. Corrections.If we got a fact wrong, email us and we will check it and fix the listing.
