Good · out of 4.0 · graded Nov 13, 2026
Best for warehouse-based A/B tests and flags
GrowthBook runs flags and A/B experiments on metrics you define in SQL against your own warehouse, as a cloud service or self-hosted. The free plan is 3 users and 1 project, Pro is $40 a seat, and it takes a warehouse and some SQL to get anywhere.
Who GrowthBook is for
- Fits if your data is in a warehouse and you can write SQL metrics
- Works for teams of three that want free flags and experiments
Who GrowthBook is not for
- Tight if you're past 3 users or 1 project, which means Pro
- Pricey if you're a bigger team, at $40 a seat and capped at 30 users and 3 projects
- Watch out: events past 1M or 2M cost $30 per million on the managed warehouse
- Watch out: SSO is Google only until Enterprise, and CDN use past 2M requests costs extra
- Not for you if you have no warehouse or SQL skills
Why GrowthBook gets a 2.8

Keep GrowthBook, or make your own?
Keep it
Nothing GrowthBook does is plain enough to make in a weekend. The 6 things listed below take a company.
It is one of the better ones too: its GPA of 2.8 is higher than 85 of the 100 other website and product analytics tools we grade. It costs $480 a year. GrowthBook is open source, so there is a third way: take its code and run it yourself.
What you could not
- Splitting visitors between versions and telling you which won.
- Connections that pull numbers from dozens of other services.
- It is priced for each person, which means accounts and billing for a team.
- It plugs into other products, Slack and dbt among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. GrowthBook’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is GrowthBook?
GrowthBook is a warehouse-native platform for feature flags, A/B experiments and product analytics. It reads results from the customer's own data warehouse using metrics defined in SQL, and can be used as a cloud service or self-hosted. Cloud plans are priced per seat, with unlimited flags, experiments and traffic on every plan.
Worth knowing
- The free Starter plan allows only 3 users and 1 project; Pro caps at 30 users and 3 projects.
- The managed warehouse includes 1M events a month on Starter and 2M on Pro, then $30 per million.
- CDN use beyond 2M requests a month on Pro costs $10 per million, and bandwidth beyond 20GB costs $1 per GB.
- SSO is Google only on Starter and Pro; custom OIDC and SCIM need Enterprise.
Key features
- Experimentation
- Unlimited A/B tests with Bayesian and frequentist statistics; Pro adds multi-arm bandits and a power calculator.
- Feature flags
- Unlimited flags with percentage rollouts and targeting; Pro adds safe rollouts with automatic rollback, and Enterprise adds ramp schedules.
- Warehouse-native metrics
- Metrics are defined in SQL on the customer's own data warehouse, with an optional managed warehouse so no connection is needed.
- Product analytics
- A metric explorer and fact table explorer on every plan, with funnel builder, user journeys and custom dashboards on higher tiers.
- SDKs and API
- 24+ SDKs, a REST API, webhooks and an MCP server, with local evaluation so flag checks do not call out to GrowthBook.
- Self-hosting
- The pricing page has a Self-Hosted tab, and the homepage describes the platform as open source with a self-hosted option.
