Why can't prices simply be converted into "cost per screen"?
Because the units differ and consumption depends on task size and model. Figma Make and Lovable use credits, v0 uses tokens, Uizard counts generations, Claude Design uses a shared time-window allowance, and Stitch publishes nothing.
Only Uizard defines a screen directly as one generation. For the others, a conversion would require fixing screen complexity and model first, and public sources almost never supply that.
How is Claude Design's allowance actually calculated?
Per AIFreeAPI's account, it shares one usage pool with ordinary chat and Claude Code, with a rolling 5-hour limit and, on paid plans, a weekly limit. Anthropic describes allowances only as multiples of Pro, without Token counts or numbers of designs.
After the limit, paid plans can enable usage credits billed at API rates; Enterprise has no included allowance and is billed entirely at API rates. This is a third-party account, so check the usage page in your own account for actual numbers.
Can these figures be trusted?
Only as reference. The main source, Mowgli, sells a design tool of its own and is a competitor; its page dates are inconsistent; neither it nor AIFreeAPI is an official page, and they contradict each other on Claude Design's free tier.
The safer approach is to use them to understand the kinds of units, then confirm actual prices and limits on each vendor's official pricing page, and keep checking, since these allowance rules change often.
How do I measure the real cost myself?
Pick three tasks you actually do and run each once in every tool, using the same written brief. After each run, note the change on the usage meter: for Claude, the share of the current session used; for Figma Make and Lovable, how many credits were deducted; for v0, the change in tokens or credits.
Then convert to one common basis, such as "percent of the week's allowance used to finish the three tasks." That figure will track your real usage better than any price table.
When comparing the cost of AI design tools, the natural question is "what does one screen cost?" I laid out the usage rules of several mainstream tools, and the conclusion is a letdown: most of them don't give an answer. They meter in different units — credits, tokens, shared time-window allowances — and some publish nothing at all.
A word on sources. The prices and limits below come mainly from a comparison page by Mowgli, with the Claude Design details also drawing on a write-up by AIFreeAPI. Mowgli sells a design tool of its own and is a competitor; both are third-party compilations that I could not check line by line against each vendor's official pages, and the Mowgli page's own dates are inconsistent (it is dated September 19 yet cites October prices). Treat the figures as illustrations of what the units look like, not as quotes.
Figma Make uses credits shared with other Figma AI features, and the cost of an action isn't fixed: it depends on the model, the task and the context. Mowgli's examples are roughly 30-plus for a font change and 100-plus for building an app from scratch. The Starter plan gives 150 a day up to 500 a month, resetting monthly with no rollover.
v0 is Token-based: Mini costs $0.20 per million input tokens and $1.20 output, Pro $2 and $10, Max $5 and $25, and monthly credits expire after 65 days. Lovable charges credits per action: plan mode 1, a button color change 0.50, authentication 1.20, a landing page 2.00; the free plan gives 5 a day capped at 30 a month. Uizard counts generations, where a project, a screen or a theme each count as one, and the free plan allows 3 a month.
Google Stitch has a free daily allowance that resets at midnight UTC, but neither the daily cap nor the cost of a single generation is published.
Claude Design has no separate pricing. Its usage comes out of the same pool as ordinary chat and Claude Code, with a rolling 5-hour session limit and, on paid plans, a weekly limit. AIFreeAPI's account is that Anthropic describes allowances only as multiples of Pro, not as tokens or numbers of designs: Max 5x is five times Pro, Max 20x twenty times, and Enterprise has no included usage and is billed entirely at API rates. After hitting a limit, paid plans can turn on usage credits, also charged at API rates.
The two third-party sources also disagree with each other. Mowgli's table lists Claude Design's free tier as "limited usage" while its body text says Design isn't on Free; Anthropic's own help page says Design is out of beta and available on every plan, Free included. The standalone claude.ai/design site closes on December 14. When sources conflict like this, go by the official page and by the usage page in your own account.
Of the six, only Uizard defines "a screen" directly as one generation. Lovable has per-action credits, but a screen isn't its billing unit; Figma Make and v0 consumption depends on task size and model; Claude Design and Stitch publish nothing that supports a conversion. So a "cost per screen" comparison table that doesn't state screen complexity and model is probably just comparing two units that don't map onto each other.
Don't compare on sticker prices. The more reliable way is to measure it yourself: pick three tasks you actually do (a landing page, a dashboard, a form flow), run each once in every tool, note the change on the usage meter, and convert it to "percent of allowance or credits used to finish these three."
If you already use Claude, remember that Design, chat and Claude Code draw on one pool, so an intensive afternoon of design can shrink what's left for coding that week. Before paying annually, validate with a month of real usage and only then decide whether to commit.
