Why I built it: As a backend developer, I often stitched together multiple APIs, transformations, and error handling manually. I wanted something like Postman, but more composable, visual, and better for multi-step workflows. So I built it.

Github Link: https://github.com/complex1/webflow-app

Live: https;//apiflux.in

What it does: Add APIs and logic as nodes.

   Connect APIs using variables across steps.

   Add custom data transforms inline.

   Debug inputs/outputs visually with history.

   Test flows live with real API calls.

   Works locally in browser also.

   Entirely open-source (MIT) — self-hostable

   I'm actively working on:

   Authentication flows

   Team workspaces

   CLI and deployment support

Whether a tool like this fits into your workflow
