Maker reviews of GrowthBook


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.

I love Growthbook! I use it mainly for the experiment tracking/reporting features and it's been really great so far. I've had zero issues with it even though it's a very early-stage product. They take a Bayesian approach to the stats side of the platform, which was a requirement for us. It's also very transparent about how the statistics work & it's easy to troubleshoot because the queries they run to fetch & transform data are readily available.
A few other highlights:
- Incredibly easy to self-host,
- There's a friendly, responsive community on Slack,
- The reports it generates are both pretty and comprehensive (both of which are critical for our PMs)
