Experimently vs GrowthBook
Both stand on a/b testing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Experimently offers broad experiment and rollout controls for teams prepared to host it themselves. Its Free Preview costs nothing on the user's AWS account, but setup includes managing deployment and SDK installation.
