GrowthBook
Simple to use, powerful, open source, and easily adaptable. Strong founding team who is also very helpful with onboarding and integration help.
It is a great feature flagging and AB testing platform - but we're probably biased as we wrote it. We use it extensively internally.
Simple, powerful, open-source, and adaptable, with a supportive founding team for onboarding and integration.
