ConfigCat vs GrowthBook
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 $110 per month (Pro)
Free tierFrom $40 per seat/month (cloud Pro, up to 30 users and 3 projects)
Free tierWhat drives the bill
The metric that actually scales your invoice.
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.
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.
Free tier
Free forever plan with a monthly config-request allowance and unlimited members.
Self-hosted open source is free with unlimited users on 1 project; the cloud Starter tier is free for up to 3 users.

Strengths

- Very simple to adopt — an afternoon, not a project.
- Broad SDK coverage including Dart and Elixir.
- 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.
Limitations
- No experimentation or analytics to speak of.
- Limited targeting sophistication compared to LaunchDarkly.
- Small vendor.
- 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.
