## 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.

## 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.

## ToolGPA grades

**GPA: 2.8 out of 4**, graded Nov 13, 2026. 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.

- **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.

## Keep it, 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.

- You could not: Splitting visitors between versions and telling you which won.
- You could not: Connections that pull numbers from dozens of other services.
- You could not: It is priced for each person, which means accounts and billing for a team.
- You could not: It plugs into other products, Slack and dbt among them, and has an API.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: The depth: we grade its features B, which means it covers the whole job.

A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it.
