If you need server-side experiments and rollout controls, you should use a feature flag / experimentation platform that supports:
- server-side evaluation
- percentage rollouts
- A/B experiments
- targeting by user or attribute
- kill switches / instant rollback
Good options include:
- LaunchDarkly — strong for server-side flags, experiments, and gradual rollouts
- Optimizely Full Stack — good for experimentation and server-side feature delivery
- Split — solid for flags, experiments, and rollout management
- Unleash — open-source option for feature flags and gradual rollouts
- Statsig — good for experiments plus rollout controls and analytics
If you want a simple recommendation:
- Best enterprise choice: LaunchDarkly
- Best open-source choice: Unleash
- Best experimentation-first choice: Optimizely or Statsig
If you tell me your stack and whether you care more about cost, experimentation, or self-hosting, I can narrow it down.
