Buyer’s guide
LaunchDarklyBest fitFree tier

The enterprise feature-flag platform, with experimentation layered on top.

Why this fits you

  • Extremely reliable flag delivery with offline fallbacks
  • Best-in-class governance: approval workflows, audit logs, role-based access.

Main limitation

  • Still the expensive option once client-side MAU volume is real, even after the move off per-seat pricing.
  • Experimentation is competent but less sophisticated than dedicated statistics platforms.
StatsigFree tier

Feature flags, experimentation and product analytics in one warehouse-friendly platform.

Why this fits you

  • Statistics engine is genuinely strong
  • Flags, experiments and analytics in one system removes a whole class of integration work.

Main limitation

  • Event-based pricing can escalate sharply on high-volume products.
  • Broad surface area means a real learning curve.
GrowthBookfrom $40Free tier

Open-source feature flags and experimentation that runs on your data warehouse.

Why this fits you

  • Warehouse-native by design
  • Self-hosting removes per-user-volume pricing entirely.

Main limitation

  • Requires a working data warehouse and someone who can define metrics in SQL.
  • Self-hosting is operational work you own.
