React Native Reanimated is expressive and powerful, but animation is a visual medium being authored as text. The feedback loop is slow: write a timing value, reload, tweak by 50ms, reload again. The gap between what you imagine and what ships is wide, and it stays wide for the entire life of the feature.

Keyframer is a browser-based keyframe editor built specifically for React Native. It borrows its design philosophy from the tools that motion and compositing professionals use, After Effects, DaVinci Resolve's Fusion, Blender's node graph, not to abstract away Reanimated, but to give it a visual surface. Draw keyframes on a timeline. Wire gestures and animations through a node graph. Watch it move in real time on a canvas running the actual Reanimated v4 worklet engine. Then export the code, idiomatic, production-ready, the kind you'd be proud to commit.

Visual tooling doesn't replace Reanimated knowledge, it gives it a faster surface to work on.
