How to choose the right Feature Flags & A/B Testing platform

Feature management vs experimentation

Flags focus on release safety; experimentation adds statistical significance.

Questions to ask:

  • Primary: release safety or growth experiments?
  • Need statistical significance calculations?
  • How many experiments per month?

Hosted vs self-hosted

Hosted sends flag data to third-party servers; self-hosted keeps it in your infra.

Questions to ask:

  • Compliance requires self-hosting?
  • PII in targeting rules?
  • Infrastructure for self-hosted flags?

Pricing model

Per-seat, per-MTU, and per-event scale differently.

Questions to ask:

  • How many developers need access?
  • Monthly active user count?
  • Open-source maintenance cost vs SaaS?
