Feature flag targeting in Supaship just got more powerful.

Until now, Supaship supported Country and Region as system properties to help you roll out changes to specific geographies. Today, we're expanding that with three new targeting attributes:

• Browser
• Operating System (OS)
• Device Type

These new properties open the door to more fine-grained rollouts and more personalised user experiences.

Why this matters

Modern applications don't behave the same across all environments. A feature that works perfectly on Chrome might have quirks on Safari. Your mobile users might need a different experience than desktop users. And sometimes, a rollout needs to start with a small, predictable audience.

With these new attributes, you can:

• Release features only to Chrome users or iOS devices
• Gradually enable a change for mobile users first
• Turn off a feature just for a problematic OS version
• Combine Browser + OS + Device + Country rules for highly precise rollouts

Start using it today

The new attributes are available immediately for all Supaship projects. You don't need to change anything in your code - Supaship automatically parses browser, OS, and device info from the feature flag evaluation request.
