Can I use FeatBit feature flags in a restricted environment without internet?

Yes, the skill provides guidance on using Offline Mode and initializing the SDK from a local JSON bootstrap file.

How does the SDK stay updated with flag changes?

The SDK uses a WebSocket connection to receive real-time updates from the FeatBit server, typically pushing changes in less than 100ms.

Is this skill suitable for Go-based frontend or mobile apps?

No, this skill is specifically designed for the FeatBit Go Server-Side SDK, which is intended for multi-user systems like web servers and APIs.

Does feature flag evaluation require a network call every time?

No, once initialized, the SDK performs evaluations locally and synchronously using in-memory data, typically taking less than 10ms.
