Which one is for you
Pick Similarweb if
- Fits if you want an estimate of how much traffic a rival gets and where it comes from
- Works for marketing teams sizing up a market by comparing lots of websites
Look elsewhere if
- Pricey if you want SEO tools, which start on the $333 plan, as the $125 plan covers traffic only
- Skip it if you need exact numbers for other sites, as these are Similarweb's estimates
- Tight if your team is bigger than one or you need more than 6 months of history, since both mean a custom package
- Watch out: the API, data feeds and integrations like Looker Studio and Salesforce need a business package with API access
- Watch out: the free version and extension show a high-level sample only, and there's no desktop or phone app
Pick SpyFu if
- Fits if you buy Google Ads and want to see what competitors bid on
- Works for agencies building branded competitor reports for clients
Look elsewhere if
- Not for you if you want to try before you pay, as there's no trial, only a 30-day money-back guarantee
- Skip it if you need daily rankings, since projects track weekly
- Tight if you're on Basic, with 1 user, 1 project, 10,000 rows per search and export, and site audits that stop at 500 pages a crawl
- Watch out: Pro + AI's $59 first month becomes $119 a month unless you pay $89 a month yearly, and extra users are $30
- Watch out: API use past the monthly credit, $40 on Pro + AI and $100 on Team/Agency, is charged to your card

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.
