- Works for teams of three that want free flags and experiments
Look elsewhere if
- Tight if you're past 3 users or 1 project, which means Pro
- Pricey if you're a bigger team, at $40 a seat and capped at 30 users and 3 projects
- Watch out: events past 1M or 2M cost $30 per million on the managed warehouse
- Watch out: SSO is Google only until Enterprise, and CDN use past 2M requests costs extra
- Not for you if you have no warehouse or SQL skills
Pick Statsig if
- Fits if you ship features behind flags and want results in the same tool
- Works for small teams that want unlimited seats on a free plan
Look elsewhere if

- Watch out: unlimited retention isn't on the free plan
- Not for you if you want a quick setup, because SDKs go into your product first

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.
