Flowstep
Sits between a design generator and a code generator: you get a screen you can edit visually, then take it into Figma or straight out as React and Tailwind. At $15 a month it is one of the cheaper entries in the category. The meter is on messages, so heavy iteration on one screen costs the same as designing five new ones.
Pros
- Generates full multi-screen flows, not single isolated mockups
- Output copies into Figma and exports as React with TypeScript and Tailwind
- Screens stay editable by hand or through further chat instructions
- Real-time collaboration on shared projects
- Publishes an MCP server so an agent can drive it
Cons
- Starter meters 80 messages a month, and every edit request spends one
- No published company entity, address or team on the marketing pages
- No design-system or component-library management
- Enterprise pricing is negotiated with nothing published
