About
Flagsmith is an open-source feature flag and remote configuration service that lets development teams manage feature toggles across web, mobile, and server-side applications. It supports user segmentation, A/B testing, staged rollouts, and remote config changes without code deployments. The platform is available as a cloud-hosted service or via on-premise and private cloud deployment.
Problem
Development teams need a reliable way to safely release, test, and roll back features without requiring code deployments or causing bottlenecks.
For
Software development teams and product engineers
How it works
Developers wrap code with feature flags and manage them through the Flagsmith dashboard, controlling rollouts by user segments, percentages, or environments in real time.
