About the product

A dozen tiny web tools that do one job well — free, no sign-up. The toolbox includes a QR code generator, barcode generator, URL encoder/decoder, robots.txt generator, JSON formatter and validator, password strength checker, and more. Everything runs client-side in the browser: no accounts, no uploads to a server, no waiting. Built for speed on desktop and mobile. New tools added every couple of weeks. Free forever.

For product owners

Promote Yhstky

Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps Yhstky in front of people instead.

  • Back in the X and Threads rotation: Yhstky gets posted again instead of once.
  • A promoted slot on the AppRater homepage, carrying a Promoted badge.
  • A direct link to Yhstky from a DR45 site (Ahrefs Domain Rating), with no redirect in between.
  • A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
  • Stays on the first screen however old the listing is, while new submissions push everything else down.

Quarterly promotion

$35USD every 3 months

Card, Apple Pay and more, through Whop. Starts straight away.

  • Cancel any time from the Whop account you paid with, or email [email protected] and we will do it.
  • The promotion starts straight away, no waiting on us.
  • Whop handles the checkout. We never see your card.
