GrowthBook

GrowthBook is an open source feature flagging and experimentation platform. Put simply, it is about catching bugs before customers do, by hand or with automation.

Who is it for? Mostly engineering and QA teams. Related areas on their profile: A/B Testing, Developer Tools and Test and Measurement. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

GrowthBook is based in Anaheim, California. You can read more at growthbook.io.

Things worth asking about: browser and device coverage, parallel runs, and reporting. Ask for a trial on your own data, not a canned demo.
