What Flagsmith actually does
Flagsmith provides a centralised dashboard, API, and client-side SDKs to manage feature flags across your software applications. It serves as a self-hosted alternative to proprietary feature toggle platforms like LaunchDarkly. You can use it to remotely control application features without needing to deploy new code.
Best fit: Development teams who want to control software releases dynamically while keeping full ownership of their feature flag data and infrastructure.
Worth knowing: Self-hosting adds operational overhead for managing high availability and ensuring your flag evaluation API remains responsive, as any downtime directly impacts your applications.
Deployment notes
Deployment typically relies on container orchestration tools like Docker or Kubernetes, requiring persistent storage for the database and a reverse proxy to handle TLS termination.
