Merge Unified vs. Integration App

Merge Unified is the leading Unified API for thousands of organizations, including frontier LLMs, Fortune 500 organizations, and other B2B SaaS companies. Merge Unified allows businesses to add hundreds of integrations to their products through a single API. Instead of building and maintaining each integration in-house, your developers can integrate once with Merge and instantly access over 220 integrations across accounting, HRIS, ATS, CRM, file storage, knowledge base, and ticketing categories.

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.
