Server-side SDKs
Last updated: 02 Sept 2025
Overview
Harness FME provides server-side SDKs that let you evaluate feature flags, run experiments, and control rollouts from your backend services.
These SDKs are designed for high-throughput, low-latency environments where feature logic must run securely and reliably without exposing rules or targeting logic to the client.
By integrating a server-side SDK, you can:
- Evaluate targeting rules securely on the server
- Maintain consistent behavior across multiple environments
- Implement feature rollouts without redeploying backend code
- Collect event data for experiment analysis
