Make rigorous experimentation easy for everyone

Experiment anywhere, your way

Lightweight SDKs for server-side, client-side, and edge experiments. Deploy by any feature flag, visual editor, or URL redirects. Set approval flows, permissions, and checklists.

Customize metrics to your business

Build any metric with SQL to track conversion, latency, retention, revenue, etc. Shared metrics library and decision framework. Set North Star metrics to track over time.

Apply rigorous statistical analysis

Run multivariate, sequential, and bandit tests with Bayesian or frequentist engines. Use CUPED, post-stratification, and SRM detection. Scales millions of users at predictable cost.

State-of-the-art stats engine

Validate ideas faster with templates, metric libraries, and approval flows. Define alerts on Slack or any channel for guardrails and failed tests.

Foster a culture of experimentation

Build more winners, ship fewer losers

Stop guessing which features matter. Use decision frameworks to know when to ship, when to rollback, and how long to test. Measure experimentation over time with meta analyses and insights.

Create trust through transparency

Query your data warehouse directly—Snowflake, BigQuery, Databricks, Redshift and more. Every query is visible through SQL. Every result is reproducible. Slice and dice metrics, add metrics retroactively to explore root causes.

Experimentation for everyone

Enable everyone to experiment like your best data scientist. No more waiting for engineering. No more ad hoc testing. Build a rigorous experimentation program anyone can deploy and understand.

GrowthBook Open-Source Platform

GrowthBook’s modular design works on top of what you have, or replaces what’s not working.

Warehouse native

Integrates with your tech stack. Analyze your data where it lives. SQL visibility.

Deployment options

Same product, same features. On cloud or fully self-hosted.

Integrations

No migration required. No changing tools. We work with your tech stack.

“GrowthBook gave us a modern experimentation and release platform that actually fits how Dropbox works. We can run analytics directly on our data lake, roll features out safely in stages, and support teams across different stacks without duplicating data or tooling.”

Alex Kalish
Engineering Manager, Dropbox

“Being able to turn a feature on and off with a flip of a switch 
is fantastic... That’s so much easier than having to do a deploy or a roll-back.”

John Resig
Chief Software Architect, Khan Academy

“People only see the wins, but there’s actually greater value in avoiding losses. We’ve stopped changes that could have cost millions.”

Merritt Aho
Digital Analytics Lead at Breeze Airways

“GrowthBook has changed the way we think about experiments... It allowed us to uplevel our code, speed up decision-making, and focus on what we do best.”

Diego Accame
Director of Engineering, Upstart

“Experimentation showed what customers actually do rather than what we assume they’ll do.”

Marek Maciusowicz
Head of Engineering, Treatwell

“We don’t need any code changes, we don’t need an app release. We just configure the new tests and launch right away.”

Filipa Batista
Product Manager, Lingokids

"We are always experimenting now. It’s a natural part of product development. This is due to GrowthBook and the ease of usage both in the UX and in the seamless integration with Snowflake/DWH."

Fredrik Jørgensen
Head of Insight, Retail Platform, Oda

"GrowthBook's results speak for themselves. Every time we do a test, we see benefits for our audiences and our partners. These posters are our one shot, and we wouldn't want to fly blind."

Head of Insight, TodayTix

“GrowthBook lets us build experiments exactly how we want. The ability to target based on culture and geography, as granular as needed, is a major win for us.”
