Feature Flags Without a Platform

The core idea

Ship the code disabled, then turn it on when ready. Rolling back becomes a configuration change rather than a redeployment.

A simple implementation goes a long way

A settings table, a helper that reads it and an admin toggle. That covers gradual rollout and the emergency off switch, which is most of the value.

Delete them

Every flag is a branch in your code. Remove each one once the feature is permanent, or the codebase becomes a maze of conditions nobody dares simplify.
