Zag.js

Verified 2026-10-06 against official website/docs and repository/license. Install a component machine such as @zag-js/tooltip plus a framework adapter such as @zag-js/react, then connect the machine to element props. Official docs explicitly list React, Vue 3, Svelte and Solid; the core models interaction behavior independently of those frameworks. MIT source. It is a lower-level interaction toolkit, not the styled Chakra UI layer or the Ark UI component wrapper; shared authorship/dependencies do not make those identical products. Editorial: useful for consistent behavior across custom design systems, at the cost of wiring markup and styles. README and docs show different API-generation examples; use documentation matching the installed package version, not blindly mixed snippets. No independent accessibility certification or integration test was performed.
