Feature Flag Dashboard
See how teams are using feature flags to control deployments and manage feature rollouts in real-time.

What are feature flags?
Feature flags (also known as feature toggles or feature switches) are a software development technique that allows you to enable or disable functionality without deploying new code. They act as conditional statements that determine which code path executes at runtime, enabling teams to control feature releases, conduct A/B tests, and manage deployments more safely.
When should I use feature flags?
Use feature flags when you want to: separate releases from deployments, conduct A/B testing, implement gradual rollouts, create kill switches for emergency rollbacks, test in production safely, target specific user segments, or manage feature lifecycles. They're particularly valuable for continuous delivery and reducing deployment risks.
How do feature flags improve deployment safety?
Feature flags improve deployment safety by allowing you to deploy code to production without immediately exposing new features to users. If issues arise, you can instantly disable problematic features without rolling back entire deployments. This reduces downtime, minimizes user impact, and gives teams confidence to deploy more frequently.
What's the difference between feature flags and A/B testing?
Feature flags are the infrastructure that enables A/B testing. While feature flags control whether features are enabled, A/B testing uses feature flags to randomly assign users to different variations of a feature to measure performance. Feature flags can exist without A/B testing, but A/B testing requires feature flags to function.
How do I implement feature flags in my application?
To implement feature flags: 1) Choose a feature flag platform like devunus, 2) Install the SDK, 3) Initialize the client with your project credentials, 4) Wrap feature code in conditional statements, 5) Create flags in your dashboard, 6) Deploy code with flags disabled, 7) Gradually enable flags for testing and rollout.
What are the best practices for feature flag management?
Best practices include: using descriptive flag names, implementing proper cleanup procedures, monitoring flag performance, documenting flag purposes, using consistent naming conventions, implementing proper fallbacks, testing flag logic thoroughly, and regularly auditing unused flags to prevent technical debt.
How do feature flags work with microservices?
In microservices architectures, feature flags can be implemented at multiple levels: service-level flags control entire service deployments, API-level flags manage endpoint availability, and client-level flags control UI features. Each service can have its own flag configuration while maintaining consistency across the system.
What's the performance impact of feature flags?
Modern feature flag platforms like devunus have minimal performance impact, typically adding less than 50ms to response times. The impact is reduced through caching, edge computing, and optimized SDKs. The performance benefits of safer deployments and faster iteration typically outweigh the minimal overhead.
How do feature flags help with continuous delivery?
Feature flags enable continuous delivery by decoupling deployment from release. Teams can deploy code continuously to production while keeping features disabled until ready for release. This allows for faster feedback loops, reduced deployment risks, and the ability to release features independently of deployment schedules.
What metrics should I track with feature flags?
Key metrics to track include: flag usage rates, user adoption, performance impact, error rates, conversion rates, user engagement, rollback frequency, deployment success rates, and business impact metrics like revenue or user satisfaction. These help optimize flag strategies and measure ROI.
How do I migrate from one feature flag platform to another?
To migrate feature flag platforms: 1) Export your current flag configurations, 2) Map flag names and rules to the new platform, 3) Implement the new SDK alongside the existing one, 4) Test both systems in parallel, 5) Gradually switch traffic to the new platform, 6) Remove the old implementation once verified.
What security considerations should I have with feature flags?
Security considerations include: encrypting flag configurations, implementing proper access controls, auditing flag changes, securing API endpoints, validating user context, preventing flag manipulation, monitoring for suspicious activity, and ensuring compliance with data protection regulations like GDPR.
How do feature flags work in mobile applications?
Mobile feature flags work similarly to web applications but with additional considerations: offline functionality, app store approval processes, and device-specific targeting. Flags are typically evaluated on app startup and cached locally, with periodic updates to ensure users have the latest configurations.
What's the difference between client-side and server-side feature flags?
Client-side SDKs run in web/mobile applications and are designed for single-user contexts. They receive pre-computed flag evaluations with obfuscated names and include user session tracing for errors, network requests, and logs. They fallback to cached configs using local storage during failures. Server-side SDKs handle multiple users, load config at startup with periodic updates from the devunus platform, and perform all flag evaluations on your own server for maximum security and performance.
How do I handle feature flag dependencies?
Handle feature flag dependencies by: documenting dependencies clearly, using flag hierarchies, implementing dependency validation, testing dependency scenarios, using feature flag management tools that support dependency tracking, and creating rollback plans that consider dependent flags.
