Krosyn
Connect your applications without the complexity.·krosyn.com
Krosyn is a data connector middleware platform for orchestrating APIs. Each connector follows a Trigger-Process-Perform pipeline: it receives an incoming webhook or API call, optionally enriches the payload with data from an external API, transforms fields with a built-in expression language, and sends the result to any HTTP-based target API. Everything is configured through a web UI, with both a visual drag-and-drop builder and a low-code editor for writing raw expressions.
