CopilotKit for Vue: the full React SDK, now native to Vue

CopilotKit has introduced a native Vue SDK, @copilotkit/vue, bringing Vue applications feature parity with its React offering through AG-UI, an open protocol connecting frontend interfaces to AI agents. The SDK includes prebuilt chat interfaces, frontend tool calling, reactive shared context, human-in-the-loop approvals, generative UI components, agent and thread management, attachments, voice support, and debugging tools, while allowing the same underlying agent to work across Vue, React, React Native, and Angular. The initial implementation was created and contributed upstream by Abel Enekes of contract-management platform fynk, who ported React tests, developed Vue equivalents, and produced a parity guide; the contribution totaled more than 62,000 lines across 244 files before being merged in May 2026. Since release, CopilotKit and community contributors have added fixes, accessibility improvements, thread features, and documentation, while fynk has deployed the SDK in production and reported reducing its codebase by roughly 11,000 lines after adopting the open protocol.
