Of course our demo is cross-platform 😉
The coolest (also hardest) part of this is that they run the exact same framework and app code, invoking the same Element PAPI, with the same threading model.

We are production ready on day1 as all our apps run on the same OSS code directly!
Ecosystem wise, we are catching up open-sourcing more batteries 🔋
Lynx is like “Blink” (the engine), and TikTok will open source its “Chromium” that wraps Lynx with more capabilities such as system APIs and navigation.
We are still naming it! “framework” feels way too overloaded
