Integration.app is designed to help product teams add native integrations to B2B SaaS applications, offering a better customer experience than Zapier by allowing users to enable integrations in one click and providing automated integration generation through AI. In contrast, Zapier relies on pre-built connectors and triggers that need to be configured manually, requiring business users to leave their app and build integrations from scratch. Integration.app also offers a world-class developer experience with API and SDK access, customizable UI, and a Connector Builder feature for extending the workspace with new connectors, while Zapier's API access is limited in terms of functionality.
