How do I report a mistake on a page?

Use the "Suggest a change" link on the page itself. It carries the page and the tool with it, so you do not have to explain which page you mean.

You do not need to be the vendor and you do not need an account. Readers spot stale prices and wrong feature claims all the time, and those reports are as welcome as vendor corrections.

What helps most is a source. "The price is wrong" takes longer to act on than "the Pro plan is 49 dollars now, see their pricing page". Corrections are checked against the vendor's own page before anything is published, so a link makes the fix immediate rather than pending.

If you would rather not use the form, the feedback page and hello@topalternatives.to both reach the same place.
