Octane (GitHub Repo)

Octane is a React replacement UI library with improved developer ergonomics. It is incredibly efficient and is designed to stay close to the speed of hand-written DOM code. Developers write with the React API they already know, and Octane's compiler removes the virtual DOM, Suspense waterfalls, rules-of-hooks bookkeeping, and hand-maintained dependency arrays before the app ships.
