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.; Tyk professional and Enterprise plan pricing not published; contact required
  • They diverge on capability: GrowthBook covers Feature flags, Tyk covers API Gateway.

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.

Tyk

  • Professional and Enterprise plan pricing not published; contact required
  • Core plan uses consumption-based model with variable costs
  • No upfront pricing transparency for production deployments

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.

Tyk: How much does Tyk cost?

Tyk offers a free 48-hour trial with no credit card required. The Core plan uses usage-based pricing on a flexible model. Professional plan offers unlimited access at a fixed price (amount not published). Enterprise plans require custom pricing.

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.

Tyk: Is there a free trial of Tyk?

Yes, Tyk provides a fully featured 48-hour free trial of Tyk Cloud that requires no credit card to start.

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.

Tyk: What deployment options are included in Tyk pricing?

All Tyk plans support Cloud, Hybrid, or Self-managed deployment options without feature restrictions, allowing flexible infrastructure choices across pricing tiers.

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.
