BlackBird

BlackBird is a multi-session browser for iOS built for QA engineers and web developers who need to test web applications across different browser environments.
Create isolated test profiles, each running in its own sandbox with separate cookies, localStorage, and cache. This ensures clean sessions with no data leakage between profiles.

Simulate different devices, platforms, and regions by configuring:
• User Agent — emulate different browsers and operating systems
• Screen Resolution — test responsive layouts and viewport sizes
• Timezone — validate time-sensitive functionality
• Language — test localization and internationalization
• Hardware Concurrency — simulate device performance characteristics

Features
• Fully isolated sessions using separate WKWebsiteDataStores
• Multiple tabs per session
• HTTP & SOCKS5 proxy support per profile
• Cookie management — view, import, and export
• Cloud sync across devices
• Team collaboration for shared test environments
• Profile folders for better organization
• Browsing history per profile

Built on WKWebView with full tab management and native navigation controls.
BlackBird includes no third-party analytics or advertising SDKs, ensuring a private and distraction-free testing environment
