Saatlas
The method
In short — Saatlas visits every product once a day. Any server response (including anti-bot protection) counts as alive; a parked domain, a DNS error or a server error count as a failure. Two consecutive failures make a listing unstable; fourteen flag it to a human, who alone can move it to the graveyard.
Who publishes Saatlas?
Saatlas is a project by SEK Studio, an independent studio that builds and runs its own software. The studio’s products are listed like any other, flagged “publisher’s product”, and go through the same checks.
Why another directory?
Because existing directories almost never remove products that shut down. Saatlas makes verification its product: every listing carries the date of its last check.
