Scoreboard · 8 tools · 6 criteria

Which design libraries can your agent actually use?

“AI-ready” is on everyone's homepage now. This scoreboard checks what's underneath, for the tools an AI-coding builder actually shortlists: does an MCP exist, can an agent try it free, does it return something buildable, and do the terms survive an automated workflow? Every non-obvious cell carries a source. Mozaika is graded with the same knife — gaps included.

Grading ourselves with the same knife

Mozaika's real gaps, July 2026: the library is ~330 web products / ~2,900 measured sections — a fraction of Mobbin's 621,500+ screens or Nicelydone's 237k. There is no mobile coverage at all. We launched in 2026: no eight-year archive, no big community, and you should weigh a young vendor's longevity like you would any other. What we'd argue back: the six columns above are about what an agent receives — and measured, per-section specs with a free tier is the combination nobody else on this board offers yet.

02 · Reading the board fairly

One honest paragraph per tool.

Mozaika

Best payload on the board for building (measured specs, 4 export formats), only real free MCP tier, cheapest paid step ($9/mo or $59 once). Smallest library, web-only, newest vendor. If you need breadth or mobile, pair us with a giant — or skip us.

Mobbin

The strongest research library ever assembled in this category — 8 years, weekly updates, real shipped UI. Its MCP mirrors its nature: reference images for inspiration, not values for construction. Billing is annual/quarterly only, a documented user sore point.

Refero

The most aggressive AI pivot in the category (MCP + Skill + Figma + styles) and growing fast. The style layer is AI-inferred from screenshots and scoped to marketing pages per their docs — fine for inspiration, weaker as a build contract. Fair monthly pricing.

Nicelydone

A decade of SaaS web-app captures with a genuinely capable 12-tool MCP — the closest structural cousin to ours. Payload is references and metadata rather than measurements, and there's no free way for an agent to try it.

Page Flows

Video walkthroughs of real journeys — a research format nothing else here replicates. But there is no machine surface at all (no MCP, no API, llms.txt 404), and the $2.95 auto-converting trial has generated documented billing complaints.

21st.dev Magic

The first mover on “components over MCP” and still the fastest way to grab a pretty React block. The contract is thin — 2–4-word queries, context-free snippets — and Claude Code reliability issues were open on GitHub as of July 2026.

Untitled UI

The strongest AI story in the kit world: MCP + CLI that installs its own well-made components. It solves “give me good parts,” not “what makes Stripe's pricing page work.” One-time pricing is refreshingly simple.

Relume

Excellent for Webflow-centric marketing-site teams; the MCP serves its own 1,500+ components. Its most-repeated public criticism is “generic” output — a style ceiling, not a tooling failure — and agent access requires a paid plan.

Method: cells were compiled in a July 2026 research pass across vendor sites, docs, pricing pages, the official MCP Registry, GitHub issues and public review threads. Where a vendor's public docs don't state something, the cell reads “not stated” instead of a guess. Mozaika's own cells describe the live product at mozaika.design.

04 · FAQ

Quick answers.

What does “agent-ready” mean for a design library?

That an AI coding agent (Claude Code, Cursor, Codex) can query it mid-build and receive something it can act on. The bar has three parts: an MCP or equivalent API exists; the payload is buildable (measured values or code, not just images to look at); and the terms — free tier, call caps, billing, license — don't break an automated workflow.

Is this scoreboard biased toward Mozaika?

It's written by Mozaika, so read it that way — but every non-obvious cell carries a source note from vendor docs, pricing pages or public reviews, dated July 2026, and Mozaika's own gaps are graded in the open: a far smaller library (~330 web products), no mobile coverage, and a 2026 launch with no long track record.

How were the cells verified — and what if one is wrong?

Cells come from a July 2026 research pass over vendor sites, docs, pricing pages, the official MCP Registry, GitHub issues and public review threads. Where a vendor's docs don't state something, the cell says “not stated” rather than guessing. If you spot an error, it will be corrected — the page is dated so you can hold it to that.
