Which one is for you

- Works for finding dead links inside Google Docs and Sheets
Look elsewhere if
- Too light for a whole site, since it checks the page in front of you and doesn't crawl
- Watch out: the free version may show product tips after a few days, and only the paid key hides them
- Tight if you want headers and footers left out or broken links rechecked in bulk, which need the $29 key
- Skip it if you're on Safari, as SelectorsHub says there's no Safari version
Pick Detailed SEO Extension if
- Fits if you check titles, headings and schema on single pages and don't want to read the source
- Works for checking hreflang on a multi-language site, alternate by alternate
Look elsewhere if
- Skip it if you want search volumes, rankings or backlinks, as it has none of its own
- 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

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.
