Overview

Webflow Apps is Webflow's official marketplace for third-party and Webflow ecosystem applications. It presents apps by recommendation, category, popularity, and free or paid availability, including automation, analytics, ecommerce, development and coding, marketing, and MCP + Agents. Developers can publish backend integrations that connect Webflow to external systems, Designer Extensions that add panels and automate design tasks inside the Designer, and Hybrid Apps that combine data and Designer operations. Apps are submitted for review with testing access, required artifacts, documentation, and a working installation flow; approved apps are published to the marketplace and updates follow the same review process.
