Alternatives to Split
Feature flagging and experimentation platform, now part of Harness.
Split ranks #6 of 8 in Feature flag platforms, with an Alt Score of 83. It is proprietary, freemium from Free and available on the web. 13 of 13 checklist rows are verified against a public source.
Split is a feature delivery and experimentation platform combining feature flags with statistical A/B testing and metrics, now part of Harness.
Engineering teams at mid-size to large organizations who need enterprise-grade feature flagging combined with rigorous, statistics-driven A/B testing — from developers doing progressive rollouts and kill switches to growth/product teams running controlled experiments on release impact.
A web-based feature management and experimentation platform (now branded Harness Feature Management & Experimentation, or FME, following Split's acquisition by Harness) offering feature flags with percentage-based gradual rollouts, user/segment targeting, one-click kill switches, approval workflows, audit logs, release monitoring with automated alerts, and self-service A/B testing with statistical significance analysis, plus a free Developer Edition and paid plans with SSO/SAML, dynamic configuration, and enterprise security controls.
You install a client-side or server-side FME SDK (available for Java, .NET, Node.js, Python, Go, Ruby, PHP, Android, iOS, JavaScript, React, and more) that downloads and caches your targeting rules locally so flag evaluations happen in-memory without a network call per request; you then define feature flags, treatments, and targeting rules (including percentage rollouts and segments) in the FME web dashboard, monitor their impact via release monitoring and impression data, and route flag events into experimentation for A/B test analysis or into third-party analytics tools like Amplitude, Mixpanel, and Segment.
