GrowthBook vs Convert Experiences

Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Entry price

From $40 per seat/month (cloud Pro, up to 30 users and 3 projects)

Free tier

From $299 per month (Growth, paid annually, 100k tested users; $399 monthly)

Trial only

What drives the bill

The metric that actually scales your invoice.

Seat-based rather than usage-based, so cost tracks the number of people using the platform rather than your traffic — which is why it stays dramatically cheaper than the commercial platforms at scale, especially self-hosted.

Priced only on tested traffic — unlimited experiments, domains and users at every tier. Growth is $299/month paid annually ($399 monthly) for 100k tested users; Pro starts around $420/month annually.

Free tier

Self-hosted open source is free with unlimited users on 1 project; the cloud Starter tier is free for up to 3 users.

15-day trial.

Strengths

  • Warehouse-native by design — no duplicate event pipeline and no data leaving your control.
  • Self-hosting removes per-user-volume pricing entirely.
  • Both Bayesian and frequentist engines with sequential testing support.
  • Unlimited experiments and seats, so nobody rations testing to save licence cost.
  • Serious privacy posture with EU hosting and no data resale.
  • Transparent, published pricing.

Limitations

  • Requires a working data warehouse and someone who can define metrics in SQL.
  • Self-hosting is operational work you own.
  • Less polished governance and approval tooling than LaunchDarkly.
  • Client-side only — no server-side experimentation.
  • No feature-flag capability.
  • Smaller vendor with a modest ecosystem.

Best for

Data-mature teams that already have a warehouse and want to avoid volume-based pricing.

Mid-sized e-commerce teams that want unlimited client-side testing with clean privacy handling.
