Hidden Costs Breakdown

1

Traffic Volume as Practical Limiting Factor

medium overage

While GrowthBook advertises unlimited experiments, traffic volume is the real constraint on experimentation throughput. Low-traffic sites cannot run statistically valid tests quickly, making the unlimited experiments claim less meaningful in practice.

even though they advertise "unlimited experiments", your traffic will be your limiting factor.

2

Data Warehouse Setup and Integration

medium integration

GrowthBook requires connecting to your existing data warehouse for A/B test analysis. Engineers must write SQL queries for experiment assignment and metric conversion data, adding setup complexity and potential consulting or engineering costs.

a data analyst or engineer connects GrowthBook to their data warehouse, then they write a few SQL queries that tell GrowthBook how to query their experiment assignment and metric conversion data.

3

Statistics Expertise Required for Analysis

medium training

GrowthBook requires users to handle statistical interpretation and decision-making themselves. Without an in-house data analyst or statistics expertise, teams may need training or external help to correctly interpret experiment results.

You'll have to handle interpretation and decision-making for all of the stats.
