Subframe
AI-native visual design tool that outputs production-ready React and Tailwind CSS code

- PLUGIN
What Subframe does
Subframe combines a drag-and-drop visual editor with AI generation to build real React/Tailwind CSS components rather than static mockups, so what's designed is close to what ships. It includes a single source of truth for a team's design system, real-time multiplayer editing, and MCP integration so coding agents like Cursor or Claude can pull generated components directly. Aimed at small teams and developers who want to skip a separate design-to-code translation step.
What you get: Drag-and-drop visual editor, Production React/Tailwind code output, Design system single source of truth, Real-time multiplayer editing, MCP integration for coding agents, Unlimited AI usage on Pro.
Typical jobs: design a UI component that ships as real React code; keep a team's design system consistent across AI-generated screens; let a coding agent pull production components via MCP; collaborate live between a designer and an engineer on one UI.
Worth knowing: Free tier is quite small (1 project, 5 pages) compared to competitors, effectively pushing serious use toward the $29/month Pro plan quickly. Verified directly against docs.subframe.com/learn/admin/pricing-and-plans on 2026-08-13 (subframe.com/pricing itself 404s and no longer hosts the table).
What users complain about: Reviewer notes that if you want total freedom over your stack or are building highly custom UI patterns, you'll still end up doing a fair amount of manual cleanup after export, and the free tier isn't enough for a real client project. (DesignWhine review)
Pricing and plan limits
Verified August 2026| Plan | Monthly | Annual (per mo) | Limits |
|---|---|---|---|
| Free | Free | Free | 1 project, 5 pages, 1 prototype, limited AI usage, 24-hour version history |
| Pro | $29 | $29 | Unlimited projects, pages, and prototypes; unlimited AI usage |
| Custom (Enterprise) | not disclosed | n/a | Unlimited, extended version history |
Where it wins
- Design output is production React + Tailwind CSS code, not a static mockup needing a separate rebuild
- MCP integration lets AI coding agents (Cursor, Claude) consume components directly
- Single source of truth for design system components keeps AI output visually consistent
- Real-time multiplayer editing supports design/engineering collaboration in one file
Where it falls short
- Free tier is capped at just 1 project and 5 pages (1 prototype), too small for real evaluation on anything but a toy project
- Highly custom UI patterns or teams wanting full stack freedom still need meaningful manual cleanup after export
- Occasional slowness reported in the editor
- No published mid-tier between $29/month Pro and custom Enterprise, leaving a gap for growing teams needing more than Pro but not enterprise features
