Feature Flags
11 providers in this category.
Feature-flag platforms toggle functionality at runtime: gating releases, running gradual rollouts, and targeting segments without a redeploy, with instant rollback when something breaks. They suit teams that want to separate deploy from release and ship continuously with less risk. Many layer A/B experimentation on top of flagging. Free tiers, open-source options, and how flags are evaluated separate the field.
