This looks great, but if I can make a suggestion, a guide in your docs on how to use this with Matomo[1] would go far. Growthbook provides Feature Flag and A/B Testing, but you have to bring your own analytics. Matomo provides those analytics and is also open source and self hosted, and would be an excellent match. There's been an issue in about integrating since September[2], and having a guide with SQL examples for using this with Matomo would take it to the next level.
