Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.8
GPA, above 85 of the 100 other website and product analytics tools we grade
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.
To get you started, here are 9 things to know about GrowthBook, taken from its own pages and our grades.
A warehouse, SQL metrics and SDKs to set up first.
- 1
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.
- 2
Paid plans start at $40 a month for each person
As its pricing page puts it: $40 per seat / month.
- 3
There is a free plan
Starter plan: up to 3 users, 1 project, unlimited feature flags, experiments and traffic, bring your own warehouse or use the managed one.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | Starter is free with unlimited flags, experiments and traffic, but Pro is $40 a seat, which is where the dearer quarter starts. |
| Free plan and trial | B | Free Starter: 3 users, 1 project and unlimited traffic. One small team can live on it. |
| Features | B | Experiments, flags, warehouse metrics, product analytics, SDKs and an API. Nothing core is missing. |
| Ease of use | C | No rating read. A warehouse, SQL metrics and SDKs to set up first. |
| Platforms and integrations | B | Web with SDKs and an API, Slack and dbt links, and a self-host option. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- Engineering teams that already keep event data in a warehouse
- Teams that want to self-host experimentation tooling
- Small teams that can stay within three users on the free 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.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
