Chaining API calls via scripts or test frameworks is hard to visualize and debug; developers spend hours stepping through logs to understand data passed between calls. Existing automation tools (scripts, Postman pre-request scripts) lack real-time step visualization and clear data flow inspection.
Why now: Teams increasingly prefer low-code/no-code automation and real-time debugging tools; visual flow debugging reduces onboarding time and maintenance costs.
A visual flow builder and runtime inspector that displays live data as it moves between nodes, lets you set breakpoints, inspect per-step request/response bodies and headers, replay individual steps, and visualize branching/conditional logic. Integrates with request collections and supports assertions/test checks. MVP: drag-and-drop flow builder, step inspector, replay and step-level logs.
Built for: Backend/frontend engineers and QA who build multi-step API automation or complex integration tests
