Hi everyone, I'm the creator of LiftKit. This project is EXTREMELY early and, as everyone has pointed out, not ready for production use. It's a solo project I work on in my free time. I'm a self-taught, so a lot of the weird choices you're seeing can be attributed to the decisions of someone who had never built something like this before.
LIFTKIT IS FREE AND OPEN SOURCE. The website's just out of date.

KNOWN ISSUES INCLUDE: - Docs are a nightmare, screenshots are ridiculous instead of real components - Components are inaccessible spaghetti
