- Too light for whole-site audits, since it inspects one page at a time
- Not for you if you browse in Safari or Edge, as only Chrome and Firefox are listed
- Watch out: the changelog's last entry is December 2024, though both stores show an update in 2026, and the interface is English only

- Skip it if you don't pay for Ahrefs, since the Ahrefs metrics need your own account
- Not for you if you're not on Chrome, as no Firefox version was found

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
