Roll out features at any pace, and know exactly how to control who sees them and when. You'll build a flag, choose a rollout strategy, read the data it produces, and keep the whole system from turning into unmanaged debt.

Feature Flags: Rolling out features safely
Learn why feature flags exist and the vocabulary you'll use in every module after this one.
Give a flag its identity, key, assignment logic, and variants. Then decide exactly who gets exposed to it and whether they stay exposed.
Pick a rollout strategy that matches your release goal. Then configure and safely test a real flag before it reaches users.
Read the data a flag produces to decide what to do next, and apply the governance habits that keep your flag inventory from turning into unmanaged debt.
