16.6Where Vibium Fits

Vibium is BiDi-native from day one. It doesn't abstract over CDP or legacy WebDriver — it speaks BiDi directly.

Traditional stack:           Vibium stack:

Test → Playwright → CDP      Test → Vibium → BiDi
       Playwright → Firefox         (same protocol for all browsers)
       Playwright → WebKit

Advantages

• No abstraction overhead — BiDi is the protocol, not a compatibility layer
• Future-proof — As BiDi improves, Vibium improves
• Cross-browser potential — When Safari completes BiDi support, Vibium works there
• Simple — One protocol, one implementation, one binary

The Trade-off

• BiDi is newer than CDP — some advanced features (network interception, coverage) are still being standardized
• Chrome's CDP is more feature-rich today — but it's not standardized
• Playwright's CDP-based approach gives you more features now at the cost of vendor dependency
