Feature flag targeting in Supaship just got a whole lot smarter and 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 capability with three powerful new attributes:

• Browser
• Operating System (OS)
• Device Type

These new properties open the door to more fine-grained targeting, safer rollouts, and more personalized user experiences.

Why this is important?

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 now:

• Release features only to Chrome users, iOS devices etc.
• 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

This update gives you the flexibility and control you need for safer experimentation and more confident deployments.

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 for the feature flag evaluation request.

Want even more control? Soon, we'll be adding support for IP address targeting.
