### [Integration App](https://www.g2.com/products/integration-app/reviews)

Integration.app presents the Universal Integration Layer: the turnkey solution for scaling your customer-facing integrations with any SaaS app, any use case. We’ve built on the strengths of previous generations by combining the standardization and turnkey nature of Unified APIs with the ease and scalability of more customized Embedded iPaaS solutions. Unlike IpaaS platforms or unified APIs, Integration.app operates at a lower level of infrastructure, giving developers multiple building blocks to assemble any kind of customer-facing integration with full flexibility and control. The platform eliminates the traditional blockers of these approaches, such as rigid, static data sets and the need to build multiple integrations one at a time. You can choose to integrate any of our 3000+ connectors across various SaaS categories (CRMs, task management, accounting, etc.) or build your own custom connector for any app with an OpenAPI spec using LLM-powered features for scraping API docs and mapping data.
