Convert Experiences vs GrowthBook

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

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

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.

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.

15-day trial.

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

• 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.

• 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.

• Client-side only — no server-side experimentation.
• No feature-flag capability.
• Smaller vendor with a modest ecosystem.

• 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.

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

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