Which one is for you
Pick Serper if

- Works for AI agents on LangChain or CrewAI that need current Google results
Look elsewhere if
- Skip it if you need Bing, Yahoo or any engine other than Google
- Watch out: credits expire 6 months after purchase, so a big pack you don't use up is money lost
- Tight if you're testing, as the 2,500 free queries come once and there's no monthly free plan
- Watch out: refunds run 7 days from the first payment, and only with under 20% of the credits used

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.
