Prompt Flow — a visual side project for flow design, trace, and integration steps (looking for feedback)

Prompt Flow is a visual side project built with React, ReactFlow, and Zustand that allows users to design and trace algorithmic flows on a canvas, replacing spoken explanations or flat text notes. Data is stored locally in the browser using IndexedDB, with no server-side database or user login required, and projects can be backed up via JSON export/import. The app includes sample templates to help users quickly understand how to model flows.

Hey everyone, I’ve been working on a side project called Prompt Flow and wanted to share it here — it’s not finished yet, but I’ve been using it day to day. The real starting point: when I’m developing an algorithm, I didn’t want to keep going with spoken explanations or flat text notes. I wanted to design a flow and see the whole process at once — so I moved to a canvas where I can answer “where does it go from here, and what happens on this branch?” in one glance. What’s in there now: Stack: React, ReactFlow, Zustand; TR/EN/RU UI; project JSON export/import. Data is intentionally simple: projects are stored in the browser IndexedDB . There’s no server-side database and no user login. Your flows stay in your own browser without signing up — use JSON export/import if you want a backup. SP/table nodes on the canvas are for modeling flows; the app itself doesn’t connect to a database. If building a flow from scratch feels heavy, there are a few sample templates inside the app — pick one and load it onto the canvas. I added those so you can see how things work faster. Happy to answer questions; I can share screenshots if that helps.
