Ship features behind a flag.
Turn features on or off, roll them out to a slice of users, and test in production without a redeploy.
Toggle a feature from the console — the change takes effect instantly, no deploy.
Ship to 5% of users, then 50%, then everyone — or roll it back in a click.
Try an idea on real users before you commit to it, without branching your code.
