Statsig vs. GrowthBook
What's the difference? Let's dive in.
Statsig's key advantages over GrowthBook are:
Most advanced experimentation, trusted by OpenAI & Notion
'Unscalable' customer obsession & support
Built for enterprises and small teams alike
Integration of analytics with experiments and flags
Warehouse-native experimentation & analytics
Key Differences
Statsig and GrowthBook both offer product building platforms with Feature Flags and Experimentation.
01
Most advanced Experimentation, Trusted by OpenAI & Notion
Statsig's experimentation, based on best practices from Facebook, is trusted as the most advanced and battle-tested Experimentation Platform available. With functionality like CUPED, Meta Analysis, A/A Testing, Stratified Sampling and more, Statsig has all of the bells and whistles for those who need them. Additionally, the ability to define metrics on top of your own warehouse data opens up new possibilities for Experimentation.
02
'Unscalable' customer obsession & support
At Statsig, we view support as one of our core competencies. Rather than a regular support system with tickets and SLAs, support is the responsibility of the whole company, with a community Slack channel free for everyone, and dedicated Slack channels included for each Enterprise customer. Along with our dedicated customer-facing Enterprise Engineering team, our senior leaders regularly respond to customer inquiries.
03
Built for enterprises and small teams alike
One of our core tenets is that we believe building products is a team sport. This is why we don’t charge based on seats: we believe everyone in the company should be in the Statsig Console, looking at dashboards, playing with data, and opting themselves in and out of new features to ensure they’re experiencing beta versions of the product. Whether you're a team of 1 or 100,000, Statsig scales with you.
04
Integration of Analytics with Experiments and Flags
Statsig Product Analytics are built to work with our Experiment and Feature Flag products, allowing you to use your flag/test 'Exposures' as analytical metrics, and breakdown other charts by flag and experiment exposure group. Plus, use our new Session Replay tooling to see exactly how each user is experiencing the product, with Flag and Test groups searchable in each session.
05
Warehouse-Native Experimentation & Analytics
Using Warehouse Native Statsig means that you can define the metrics that back your experiments, feature flags and product analytics (beta) directly on top of your warehouse data, with support for Snowflake, Bigquery, Redshift, Databricks, and Athena. You can also use Statsig's infrastructure to track events, metrics and exposures, and store them in your own warehouse.

At Notion, we're continuously learning what our users value and want every team to run experiments to learn more. It’s also critical to maintain speed as a habit. Statsig's experimentation platform enables both this speed and learning for us.

We evaluated Optimizely, LaunchDarkly, Split, and Eppo, but ultimately selected Statsig due to its comprehensive end-to-end integration. We wanted a complete solution rather than a partial one, including everything from the stats engine to data ingestion.
