NudgeKit

NudgeKit is a web app (with a lightweight JS/Swift/Kotlin SDK) that helps product teams design, ship, and measure microinteractions: button states, haptics, toasts, inline validation, loading skeletons, empty states, and subtle animations. It provides a library of production-ready patterns, a visual editor to tune timing/easing/copy, and an experiment layer to A/B test microinteraction variants without rebuilding the whole UI. The core value is measurement: it ties microinteraction changes to real metrics like form completion, rage clicks, drop-offs, and time-to-success. It also flags “microinteraction debt” by detecting missing states (no error state, no disabled state, no network retry) from event patterns. This is not a design toy; it’s a workflow tool that connects design intent to shipped behavior and outcomes, with guardrails so teams don’t over-animate and hurt performance or accessibility.
