GrowthBook vs ConfigCat

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

From $110 per month (Pro)

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.

Plans run Free, Pro $110, Smart $325, Enterprise $900 and Dedicated $4,500 a month. Unlimited seats and unlimited flag reads on every plan, including free — unusual and genuinely valuable for wide access; paid tiers mainly raise flag, environment and product limits.

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

Free forever plan with a monthly config-request allowance and unlimited members.

• 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 team members at every tier, so product and support can toggle flags too.
• Very simple to adopt — an afternoon, not a project.
• Broad SDK coverage including Dart and Elixir.

• 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.

• No experimentation or analytics to speak of.
• Limited targeting sophistication compared to LaunchDarkly.
• Small vendor.

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

Teams that want simple, cheap flags accessible to the whole company.
