GrowthBook is an open source feature flagging and experimentation platform. Safely release features to production and measure the impact on your key metrics.
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)
