Tray is an iPaaS solution that offers a large connector library and a rich visual workflow builder, but its native embedded integrations come at a premium price. Tray Embedded allows customers to build partially-native integrations, but it has limitations such as lack of custom connectors, scalability issues, and limited API capabilities. However, Tray's workflow builder is a favorable choice for building small number of lightly customizable integrations. Integration.app is a more comprehensive alternative that offers configurable connectors and integration logic, well-developed debugging and troubleshooting capabilities, and supports extensive customization. Paragon provides an embedded iPaaS solution with on-premise deployment options, a rich catalog of native integrations, and a more developer-friendly API. Merge offers a unified API for generic integrations, while Workato is a low-code iPaaS solution that caters to both technical and non-technical individuals. When choosing a native integration solution, it's essential to weigh the pros and cons of each option and consider factors such as customizability, scalability, and pricing.
