Subframe
A visual editor for building React components against your design system.
NOT REALLY
why this verdict
Keep paying — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the design job, so this one still earns its $19/mo.
- A named launch, not a vibe named, unlinked
- AI UI generators output code directly from a prompt. Anthropic, April 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 1 of 2 listed replacements have a usable free tier: v0.
- What the call is worth $228/yr
- $19/mo at the entry paid tier — $228 a year per seat.

The backstory
Subframe's argument against prompt-to-UI is consistency: it edits against your actual components and tokens, so the output matches the rest of the product instead of inventing a new button. For teams with a design system, that constraint is the whole point.
