Membrane, formerly Integration App, is an AI-powered platform designed to build, test, and maintain product integrations automatically. It enables teams to describe the integration they want and watch the system generate production-ready code, workflow logic, and real-time sync behavior. With its Agent, Engine, and Packages, Membrane provides everything from autogenerated integration logic to drop-in code modules that developers can fully own and deploy anywhere. The platform supports any API on the internet, interprets documentation autonomously, and eliminates the need to build webhook handlers, retries, or monitoring systems manually. Companies rely on Membrane to deliver fast, scalable, and deeply customizable integrations across CRM tools, HRIS platforms, financial systems, and hundreds of other apps. By replacing weeks of engineering effort with minutes of AI-driven automation, Membrane transforms how modern software teams ship integrations.
