Flagsmith helps you release features with confidence and manages feature flags across web, mobile, and server-side applications. Use the Flagsmith-hosted API, deploy to your own private cloud, or run on-premise.

Flagsmith provides an all-in-one platform for developing, implementing, and managing your feature flags. Whether you are moving off an in-house solution or using toggles for the first time, Flagsmith will provide both power and efficiency.

Manage Flags across multiple platforms

Flagsmith makes it easy to create and manage feature toggles across web, mobile, and server-side applications. Wrap a section of code with a flag, and then use Flagsmith to manage that feature.

Powerful Segmenting rules

Manage feature flags by development environment and by user group—including individual users, a segment of users, or a percentage. This allows you to implement practices like canary deployments.

Drive A/B and Multivariate Tests

Multivariate flags allow you to use a percentage split across two or more variations for precise A/B/n testing and experimentation.


View and control Flagsmith flags directly from your existing Datadog dashboards.


Send flag change events from Flagsmith into your Datadog event stream with the Datadog Flagsmith integration.
