Target feature variants based on what users do, not just who they are.

Mixpanel Feature Flags supports several targeting options, including cohorts (audiences based on behavior or attributes) and runtime properties (conditions like OS, app version, or browser).

With Runtime Events, you can target users based on specific Mixpanel events in real time. When a user triggers a designated event, they receive the active variant on the next flag evaluation, without waiting for a cohort refresh.

This unlocks serving features based on time-sensitive, behavior-driven patterns such as:

• Onboarding flows: Show tutorial content after a user completes their first action
• Progressive feature unlocking: Unlock advanced features after users complete key milestones
• Conditional promotions: Display special offers after a user makes their first purchase
• Behavior-gated experiments: Run experiments only on users who have demonstrated engagement

You can also fine-tune Runtime Events with optional settings like First Time triggers (with session vs. indefinite duration) and event property filters (for example, triggering only on purchases over a certain amount or specific page paths).

Availability: Runtime Events are designed for client-side SDKs that can monitor events in real time. Server-side implementations are not supported.

• Web SDK: available now
• Mobile SDKs: coming soon
