Flowstep

Flowstep is an AI design canvas that generates code-backed UI screens from prompts, product documents, images or links, built for developers and product designers who work alongside coding agents. Its key idea is that a design and its code should never drift apart: every frame on the canvas is real code you can preview or export. It also plugs into the agents developers already use through MCP, so design can happen from inside the editor.

What is Flowstep used for?

Flowstep is used to design interfaces quickly and keep them in sync with the codebase, rather than producing static mockups that must be rebuilt.

• Generating multi-screen UI from a prompt, an attached spec, a screenshot or a product URL
• Editing by chat or by clicking an element on the canvas and changing it directly
• Setting a theme and file instructions once so every generation follows your colors, tone and layout rules
• Previewing interactive designs and exporting the code to ship
• Driving the canvas from Cursor, Claude Code, Windsurf or Codex through the Flowstep MCP server
• Copying frames into Figma with a keyboard shortcut, or importing Figma frames as editable screens

Who Flowstep is best for

Flowstep is a good fit for developers who design their own interfaces, small product teams without a full-time designer, and designers who work closely with engineers using AI coding tools. Teams that live entirely in Figma and do not want code in the loop may prefer a pure design tool.

Flowstep pricing

As of October 2026, Flowstep has a free plan for trying it out with limited messages, multi-screen generation and projects. Starter costs $15 per month on monthly billing and includes 80 messages per month with unlimited multi-screen generation, projects, exports and copy to Figma, with higher message tiers available. Annual billing saves up to 20 percent. Every prompt counts as one message, and errors do not count. Enterprise plans with advanced security, compliance, dedicated support and volume pricing are available by booking a call.

Limitations to keep in mind

• Message caps mean long iteration sessions can hit the Starter limit
• Free plan limits are described only as limited, so you have to test to find them
• It focuses on UI and front-end code, not backend logic
• Prices are shown only in US dollars for now

Flowstep vs alternatives

v0 by Vercel and Lovable are better if you want a full app with hosting from a prompt. Onlook is the closest match for designers who want to edit a real React codebase visually. Cursor is a code editor first, and pairing it with Flowstep over MCP is one of the main use cases rather than a straight competition. Flowstep wins when you want a visual canvas that stays 1:1 with code and can be driven by the agents already in your workflow.

Tips for getting started with Flowstep

Set up your theme and file instructions before generating anything, so you do not have to repeat brand and layout rules in every prompt. Attach a PRD or a screenshot rather than describing everything in text, since Flowstep is built to read context. If you use Cursor or Claude Code, connect the MCP server early so you can generate screens without switching tools. Copy a finished frame into Figma when stakeholders need to comment there.

Flowstep FAQ

Is Flowstep free?

Yes, Flowstep has a free plan with limited messages and projects. The Starter plan costs $15 per month for 80 messages.

Does Flowstep work with Cursor and Claude Code?

Yes, Flowstep's MCP server connects Cursor, Claude Code, Windsurf and Codex so you can generate and edit designs from your editor.

Can Flowstep export to Figma?

Yes, you can paste any Flowstep frame into Figma with a keyboard shortcut and import Figma frames as editable screens, with no plugin needed.

What is the best alternative to Flowstep?

Onlook is a strong alternative for visual editing of React code, and v0 by Vercel is better for generating a full app from a prompt.
