Should I use feature flags or staged rollouts?

They solve different problems, so often both. Use feature flags for fine-grained control over individual features, shipping a feature disabled, enabling it gradually, or instantly disabling a misbehaving one without a full release. Use staged rollouts to limit a whole update's blast radius, releasing to a small slice first and expanding if healthy. They combine well: stage a rollout to limit exposure, and use flags to control specific features within it, for layered release safety.

How do feature flags reduce release risk?

By letting you control or kill a specific feature without shipping a new build. You can ship a feature disabled and enable it when ready, enable it for only some players, or, crucially, instantly disable a feature remotely if it causes a crash spike or other problem, no emergency release needed. This fine-grained, per-feature control complements staged rollouts (which limit whole-update exposure), so together they give you layered ways to manage and contain release risk.

Feature Flags vs Staged Rollouts

Quick answer: Feature flags toggle specific features on or off independently of releases; staged rollouts release a whole update to a growing percentage of players. Flags control features; staged rollouts control update exposure.

Feature flags and staged rollouts are both techniques for reducing release risk, but they work at different granularities, individual features versus whole updates. Knowing the difference helps you use each. Here's the comparison.

What Feature Flags Do

Feature flags (toggles) let you turn specific features on or off independently of your release, without shipping a new build. You can ship a feature disabled and enable it later, enable it for some players, or disable a misbehaving feature instantly if it causes problems. Flags give you fine-grained control over individual features.

The strength of feature flags is the ability to control or kill a single feature without a full release, if a flagged feature causes a crash spike, you turn it off remotely. Bugnet's per-version monitoring helps you spot when a feature is causing problems worth flagging off. Flags operate at the feature level.

What Staged Rollouts Do

Staged rollouts release a whole update to a growing percentage of players, a small slice first, then expanding if it's healthy. They control exposure to an entire release, limiting how many players a bad update reaches before you catch it. Staged rollouts operate at the update level, the whole build, not individual features.

Bugnet's per-version crash tracking pairs with staged rollouts: you watch the new build's crash rate on the first slice and expand or halt accordingly. Staged rollouts limit the blast radius of a release, a different granularity from feature flags' per-feature control.

How They Differ and Combine

They work at different levels: feature flags control individual features (toggle one on/off anytime), staged rollouts control whole-update exposure (limit how many players get a release). One lets you kill a single feature; the other limits how widely an update spreads. They're complementary risk-management tools.

They combine well: stage a rollout to limit exposure, and use flags to control or kill specific features within it. Bugnet's monitoring supports both by catching problems fast. So use feature flags for fine-grained per-feature control (especially to disable a misbehaving feature without a release) and staged rollouts to limit a whole update's blast radius, often together for layered release safety.

Feature flags toggle specific features on/off independently of releases (kill a bad feature without a build); staged rollouts release a whole update to a growing percentage (limit blast radius). Different granularities, complementary, often used together.
