Feature flags let you control your application’s behavior from GrowthBook, without deploying new code. Target specific users, gradually roll out changes, or run A/B tests on the client or the server. Feature flags decouple deploys from releases. Release code more frequently and with less risk by launching to a subset of users, ramping up gradually, or turning any change into an experiment.Documentation Index

Getting Started
To use feature flags, set up an SDK Connection, then explore the docs below.Learn the Basics
- Fundamentals — Keys, feature types, default values, and publishing
- Environments — Control which features are enabled per environment (dev, staging, production)
Set Up Targeting and Rules
- Rules — How rules work, choosing a rule type, and configuring forced values, rollouts, experiments, and scheduling
- Targeting Conditions — Define who sees a feature using attributes, conditions, and saved groups
- Safe Rollouts — Release features with automatic guardrail monitoring
- Prerequisites — Gate features based on the state of other features
Manage Flags at Scale
- Publishing & Approval Flows — Drafts, revisions, merge conflicts, and requiring approvals
- Stale Feature Detection — Identify flags that may no longer be in use
- Code References — Find where flags are used in your codebase
- Feature Diagnostics — Inspect feature evaluations in production
- Custom Hooks — Extend GrowthBook with custom validation logic (self-hosted Enterprise)
