Uses for Real-Time Flags

Kill switches

Implement robust kill switches that react immediately to changes in flag state. Turn off features and instantly remove them from the application for all users.

Quickly adjusting features

By default, users will see changes to features (e.g. a chat widget) when they land on a page or complete an action like logging in.

Enabling real-time builds on this by also adjusting features as soon as they are changed in the dashboard.

Managing Features in Real Time

Manage features so users see updates on your website/app immediately. Make sure they don’t continue to see unchanged features. For example, let’s say you’re showing status updates or managing a time-sensitive feature (e.g. related to an event). Real-time feature flagging lets you update your users instantly.

Something to Keep in Mind

Managing features in real time means your application’s UI could change quite a lot in real time as well. As people are adjusting flags, users may notice changes as they’re using your app/site.

Flagsmith has enabled us to get new features into production more quickly and start gathering feedback from real users.

Using feature flags have allowed us to always make sure the trunk branch in git is deployable. This is a particular relief in these challenging times (under a partial COVID-19 lockdown), because we can't always check with everyone on the team.

What does toggle flag mean?

A toggle flag (also called a feature flag or feature toggle) is a software development technique that allows you to turn features on or off without deploying new code. Think of it like a light switch for your application features—you can instantly enable or disable functionality for all users, specific user groups, or individual users through a simple flag toggle action.

How do real-time flag toggles work?

Real-time flag toggles use live connections to push changes instantly to your applications. When you flip a flag toggle in the dashboard, the change is immediately synchronised across all environments and platforms without requiring users to refresh or restart their sessions.

What are the differences between feature flags vs. feature toggles?

Feature toggles are generally simpler on/off switches that control whether a feature is enabled or disabled—think of them like basic light switches. Feature flags, on the other hand, are often part of broader feature management systems like Flagsmith that include advanced capabilities like user targeting, gradual rollouts, A/B testing, analytics, and governance controls.
