Switch On Feature Management·split.io

Split.io is a feature management and experimentation platform that lets teams create, target, and manage feature flags at enterprise scale. It connects feature flags to impact data so teams can monitor gradual releases, get alerts when a specific flag is causing problems, and run experiments (A/B tests) to see whether software changes are making things better or worse. The product is now part of Harness and is referred to in Harness's documentation as Feature Management & Experimentation (FME).
