Overview
Zapier is a hosted automation service built around trigger-and-action workflows. It connects thousands of business applications, supports no-code and low-code automation, and provides tools for custom actions and private integrations. Its current product also includes AI steps, AI agents, and Zapier MCP, which lets supported assistants use connected apps with controlled permissions. Zapier is proprietary software delivered as a cloud service; its public repositories cover tools such as the MCP distribution, SDK, CLI, and agent skills rather than the hosted product itself.
