Feature flags (also called feature toggles) let development teams release features safely without redeploying code. They power gradual rollouts, A/B testing, and fast rollbacks when things go wrong.

But as systems grow, feature flags often become a source of hidden complexity. Flags pile up, naming breaks down, and unclear ownership leads to risky changes in production. What starts as a simple toggle system can quickly turn into long-term technical debt.

This guide walks through seven common feature flag mistakes and the best practices to avoid them, so your system stays clean, predictable, and safe to work with.

Feature flags help teams release features safely and quickly, but if left unmanaged, they can become stale and accumulate technical debt. To keep your codebase clean, you can use the Zombie Flags page, the Zombie Flags Report, and the Zombie Flags API. Let’s take a closer look at each of them.

Can naming feature flags be hard?

Yes. Just like variables in programming, naming feature flags can get tricky if you don't follow a naming standard. When feature flags don't have good names, it can be difficult for people using them to remember what they do.

In this guide, we'll walk through feature flag naming conventions and best practices that help teams manage flags at scale.
