Can I run multiple tests at once?

Technically, yes. There are cases where this is okay to do. However, we typically recommend running tests one at a time to avoid any interaction or substitution effects across the groups that could skew results. For example, if you run multiple tests, a user could end up in different test groups for each test, which could mean they get the lower price for Product A and the higher price for Product B. This could result in a substitution that you would not have seen had you run one test at a time.

On a related note, you can have multiple products in the same test, which would keep users in the same group across all products being tested.

❗Note that Basic Plans are limited to one test at a time. Please reach out to us at if you have questions about this limitation.
