Show HN: FlowCode – Visual Flowcharts That Generate and Execute Python

https://southernadd-cmyk.github.io/flowCode/
1•adamclement•2h ago
I built FlowCode, a browser-based tool for teaching programming logic. You drag flowchart blocks, connect them, and:

the flowchart executes step-by-step

variables update live in a watch window

Python code is generated automatically

loops (for / while) and if / elif / else are auto-detected

you can save/load as JSON

no backend — everything runs client-side

Demo: https://southernadd-cmyk.github.io/flowCode/

It’s aimed at:

computing / CS teachers

students learning sequencing & control flow

anyone who thinks in diagrams first

A few things it currently supports:

Start/End, Process, Variable, Decision, Input, Output nodes

live execution highlighting

variable trace table

zoom / pan canvas

import/export example diagrams

loop pattern detection (including basic for inference)

I’d really value feedback on:

UI clarity for students

whether execution semantics feel intuitive

missing blocks you’d expect (functions & arrays maybe coming soon)

browser performance with larger charts

anything confusing or obviously wrong

I’m especially interested in teacher perspectives using this with classes.

It’s a pure HTML/JS project — no accounts, no tracking, no ads.
