The short version

  • Only GrowthBook has a free tier, so it costs nothing to try first.
  • Each has a real cost: Crazy Egg the Starter plan at $29 a month covers 5,000 pageviews and 50 snapshots, which a modest site exhausts quickly; GrowthBook warehouse-native analysis is only an advantage if you have a warehouse with clean event data in it; without one, GrowthBook has nothing to compute against and you are back to buying an event-collecting platform.
  • They diverge on capability: Crazy Egg covers Heatmaps, GrowthBook covers Feature flags.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Crazy Egg

  • The Starter plan at $29 a month covers 5,000 pageviews and 50 snapshots, which a modest site exhausts quickly
  • All plans are billed annually rather than monthly
  • There is no free tier, only a trial
  • Reaching 500,000 pageviews means the Pro plan at $249 a month

GrowthBook

  • Warehouse-native analysis is only an advantage if you have a warehouse with clean event data in it; without one, GrowthBook has nothing to compute against and you are back to buying an event-collecting platform.
  • Metrics are SQL, so a marketing or product team without data engineering support cannot define or fix them, and a badly written metric silently produces a confident wrong answer.
  • Cloud Pro bills per seat and then adds CDN request and bandwidth overages, so a high-traffic site can find the variable component exceeds the seat cost it budgeted for.
  • Self-hosting means you own the Mongo database, the SDK endpoint availability and the upgrade path, and a flag service that is down is a production incident, not an analytics inconvenience.
  • The statistics engine exposes real choices, Bayesian versus frequentist, sequential testing, variance reduction, and the tool will not stop a team that configures them wrongly, so it rewards statistical literacy and punishes its absence.

Answered from the vendors’ own pages

Crazy Egg: How is Crazy Egg priced?

Crazy Egg starts at $29/month for 5,000 tracked pageviews and 50 recordings. Pricing scales to $599/month for Enterprise tier. A/B testing available from $99 plan up. Annual billing required with no monthly option. 30-day free trial available.

Source
GrowthBook: Is the self-hosted version actually usable, or crippled?

It is genuinely usable: unlimited users, flags and experiments on one project under an MIT licence. The paid tiers add multiple projects, SSO, audit logs and support.

Crazy Egg: What features does Crazy Egg include?

Crazy Egg provides heatmaps showing user clicks and scrolls, session recordings, A/B testing from the Plus tier up, and unlimited domains and team members across all plans.

Source
GrowthBook: Do I need a data warehouse?

For experiment analysis, effectively yes. Feature flagging works without one, but the reason to choose GrowthBook over a flag-only tool is the warehouse-native statistics.

Crazy Egg: Does Crazy Egg offer a free trial?

Yes, Crazy Egg offers a 30-day free trial for all new users to test heatmaps and session recordings before committing to a paid plan.

Source
GrowthBook: How does the cost compare with LaunchDarkly or Optimizely?

GrowthBook charges per seat rather than per monthly active user or per tracked event, so cost stops scaling with traffic. At high volume that difference is large.

GrowthBook: Does it support mobile and server-side flags?

Yes, there are SDKs across JavaScript, React, Python, Go, Ruby, PHP, Java, Kotlin, Swift and more, covering client, server and mobile evaluation.
