The short version

  • Each has a real cost: 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.; Matomo the self hosted Community Edition is free but excludes A/B testing, heatmaps, session recording, cohorts, crash analytics and multi channel attribution, all of which are paid plugins
  • They diverge on capability: GrowthBook covers Feature flags, Matomo covers Web analytics.

Where each one falls short

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

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.

Matomo

  • The self hosted Community Edition is free but excludes A/B testing, heatmaps, session recording, cohorts, crash analytics and multi channel attribution, all of which are paid plugins
  • Premium plugin bundles for self hosted installs run from 275 EUR a month for 4 users to 3,400 EUR for 50
  • Cloud pricing is banded by monthly hits, and anything above 10 million requires contacting sales
  • Self hosting places all operation and upgrades on the operator while still needing paid plugins for the advanced features

Answered from the vendors’ own pages

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.

Matomo: How much does Matomo cost?

Matomo Cloud starts at EUR 29 per month for the Starter plan, which covers 50,000 hits per month. Matomo On-Premise has a free Community edition, with paid bundles from EUR 275 per month for up to 5M hits and 4 users.

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.

Matomo: Is Matomo free?

The On-Premise Community edition is free forever with unlimited users and hits, supported through the forum only. Matomo Cloud is a paid service, though a free trial with access to all core features is offered.

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.

Matomo: What is the difference between Matomo Cloud and On-Premise?

Cloud plans include hosting, maintenance, automatic updates and daily backups, priced by monthly hits from EUR 29. On-Premise is self-hosted, free in its Community edition, with paid bundles adding support and higher user counts.

Source
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.

Matomo: How many hits do the Matomo On-Premise bundles cover?

The Team bundle covers up to 5M hits per month and 4 users at EUR 275 per month. Business covers up to 30M hits and 20 users at EUR 1,450. Enterprise covers up to 100M hits and 50 users at EUR 3,400.
