About Split

Split was a feature delivery platform that combined feature flags with automatic measurement: every flag rollout could be tied to metrics, so teams saw whether a release hurt performance or improved conversion without setting up a separate experiment. It was popular with engineering organisations practising progressive delivery. Harness, the software delivery platform, acquired Split in 2024 and now sells it as Harness Feature Management & Experimentation, alongside its CI/CD, configuration and AI tooling. Existing Split customers continue on the platform, and new customers buy it through Harness, on quote-based plans. People still search for Split by name, so it is listed here. It suits teams already using Harness or wanting flags tightly integrated with pipelines; teams that want a standalone or open-source flag tool may prefer alternatives. It runs in the browser with SDKs for most languages.

Best for: Engineering teams on Harness that want flags tied to release metrics.
