What does Flagsmith do?

Flagsmith is an open source feature flag and remote configuration platform that helps development teams control how and when features are released to users. Instead of deploying new code for every change, developers can wrap features in flags and toggle them on or off for specific environments, user segments, or percentage groups. This allows for canary releases, A/B testing, and gradual rollouts without requiring app store updates or full deployments.

The platform supports multiple programming languages and frameworks including React, Node.js, Python, .NET, iOS, Android, and more through comprehensive SDKs. Flagsmith stands out by offering both cloud-hosted and self-hosted options, giving teams flexibility in how they manage their infrastructure. The remote configuration capability lets teams modify application behavior in real-time, changing everything from UI elements to payment options without touching code.

Development teams at companies like Ford, Okta, and Citi use Flagsmith to reduce deployment risks, test features with specific user groups, and maintain control over production releases. It's particularly valuable for teams practicing continuous deployment who need to separate feature release from code deployment, ensuring smoother and more controlled software delivery.
