Flowstep 1.0 - AI design engineer. Design & ship real UI.

Flowstep is the AI design engineer for developers and technical designers tired of rebuilding designs in code. Prompt or edit on an infinite canvas. Export production code or connect with your agents and apps via MCP. What you design is exactly what ships.

How does this compare to pencil dot dev or Claude design?
Svyatoslav Polishchuk

@lakshminath_dondeti Thanks for the question.

It's different shapes for different workflows. Pencil is a design canvas inside your IDE. Claude Design is broader in scope (decks, prototypes, one-pagers) and bundled with a Claude subscription.

We're more focused: a standalone web app for UI generation, with clean React/Tailwind output and one-click Figma export. Better designing and iteration experience. No IDE setup, no Claude plan required to try it.

@karabeen do you have an in house model?
Svyatoslav Polishchuk

@lakshminath_dondeti we use a mix of models, depending on the task and stage.

👋 Matt here, co-founder of Flowstep.

Last year, we shipped Flowstep as an AI designer. But you kept telling us the same thing:

"it gets me 80% there, then I rebuild the whole thing in code"

We fixed that.

Flowstep is now an AI design engineer.

→ Prompt or manually edit on an infinite canvas

→ Get production React + TypeScript + Tailwind + shadcn

→ Export the code, or pipe it into Cursor / Claude Code / Windsurf via MCP

Why this exists: The process of fast iteration, multiple concepts next to each other, full control in an infinite canvas 🤌 You shouldn't have to give up that experience because of a translation layer. That's why design and code are the same thing in Flowstep.

Free to try at flowstep.ai, paid plans available from $15 p/m.

💡 Bright idea

to answer your question: the one thing usually missing in these tools is state management. if flowstep can help scaffold the basic useState or useEffect logic while i'm building the ui on the canvas, i’m never opening figma for web work again. definitely checking out the free trial today.. @clannachan

Design to UI without the handoff gap is a holy grail. Does it write a production-ready code or still need a dev pass before shipping?
Svyatoslav Polishchuk

@anusuya_bhuyan Honest answer – it depends on your standard for production-ready code.


Flowstep outputs clean React + Tailwind you can ship as-is for most UIs. API and state wiring – if the app needs any – that's still on devs. At least, today. So the real question is: where's your line?

Aarav Pittman

This is the kind of shift that actually matters less about designing screen more about desigining shippable system.Curious how reliable the generated code is in real projects.

.

Svyatoslav Polishchuk

@aarav_pittman That's the framing we care about. The export is clean React + Tailwind — it's a starting point you can build on, not a black box. Easiest to just export something and judge it yourself ;)

Maali Baali

Love the canvas first approach .Most tools still feel constrained but this seems much closer to how designers developers actually think and iterate.to

Svyatoslav Polishchuk

@maali_baali Exactly — fast iteration is the whole bet. Each step should get you closer to the real product, not further into a mockup.
