Hi HN,

I'm the creator of Foldkit, a TypeScript framework built on Effect and inspired by the Elm Architecture.

This page compares the same pixel art editor implemented in React and Foldkit side-by-side.

Rather than focusing on benchmarks or isolated examples, I wanted to compare what building and maintaining the same application feels like in each architecture. The comparison includes state management, UI, async operations, side effects, application structure, and testing.
