Feature flag architecture: beyond simple on/off switches

**Note:** This blog post is intended for technical audiences. If you're not familiar with feature flags, their importance, or how to implement them, please start with the basics before proceeding.

Introduction to Feature Flags

Feature flags are a powerful tool for managing changes to software features in a production environment. They allow developers to turn features on or off without redeploying code, which is crucial for testing, A/B testing, and managing releases. This post explores various types of feature flags and discusses how to implement them effectively, particularly focusing on Bastionary, a self-hosted authentication and billing platform that also offers feature flags.

Basic on/off Switches

The simplest type of feature flag is an on/off switch. This flag toggles a feature on or off for all users. While effective, it lacks the flexibility needed for more complex feature management scenarios. ```html
