Marketplace · Feature Flags & Experimentation
Feature flags decouple deploy from release and let you ship safely; experimentation platforms turn the same flag system into A/B tests with statistical significance built in. Founders who run them well ship faster with fewer rollbacks and learn what works from data, not opinion. Don't adopt until you actually have a release cadence that's friction-bound by 'all-or-nothing' deploys.
