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.
Under the hood: Built with Node.js, Nginx, and Vue
Zero config setup (no login needed) Entirely open-source (MIT) — self-hostable
I'm actively working on:
Authentication flows
Team workspaces
CLI and deployment support
Would love feedback from fellow developers and builders here. Especially interested in your thoughts on:
What API debugging or chaining pain points you haveWhether a tool like this fits into your workflow
What you'd need before using it in production
