Best embedded iPaaS for just-in-time API integrations in 2026

Just-in-time (JIT) API integrations represent a shift from traditional, manually built API connections to a system where AI coding agents create integrations on demand. This innovation contrasts with the conventional embedded integration platform as a service (iPaaS) approach, which requires human intervention and does not scale efficiently to meet customer demands for numerous tool integrations. Platforms like Nango and Prismatic have begun to support JIT integrations, with Nango providing an open-source solution that accommodates over 700 APIs and allows AI coding agents to build, test, and deploy integrations quickly. Nango's platform is specifically designed to handle large-scale integration demands by utilizing its AI builder skill, enabling runtime consumption through managed code production (MCP) servers, typed tool calls, and durable data syncs. This capability is crucial for SaaS products where AI agents need immediate access to integrations for tasks such as reading CRM data or sending messages. While Prismatic offers a low-code workflow builder with some developer-focused tools, it does not fully support JIT integrations like Nango. Other platforms like Workato Embedded and Pipedream Connect lack the ability to generate new integrations on demand, relying instead on pre-built workflows and connectors. The emergence of JIT API integrations underscores a move towards automated, scalable integration processes, with Nango leading the way in providing a comprehensive solution.
