Best AI integration platforms in 2026

AI models, despite their power, require integration platforms to connect with external tools for effective AI product development. An AI integration platform acts as middleware, linking AI functionalities with third-party APIs like Salesforce or Slack, and differs from traditional iPaaS tools by focusing on embedding within products to manage OAuth flows and provide APIs for AI agents. Key requirements for these platforms include continuous data synchronization for Retrieval-Augmented Generation (RAG), real-time triggers for proactive actions, and robust interfaces for tool execution. The text evaluates four platforms: Nango, Pipedream Connect, Arcade, and Workato Embedded, highlighting their strengths and weaknesses. Nango is noted for its comprehensive AI agent support and developer-centric infrastructure, Pipedream Connect for its serverless workflows, Arcade for lightweight tool-calling, and Workato for its extensive connector library. The choice of platform depends on the specific requirements of the AI product, such as the need for deep context, real-time reactivity, and reliable execution.
