## Verdict

- Choose Lazyweb if you want an agent-first design research library with 281k+ real app screens, app trees, Design.md-style app files, and screen-version history. Human browsing and MCP setup are free; non-Pro reports are partial and Pro reports are full. [3](https://design.lazyweb.com/)
- Choose shadcn/ui if you need editable UI primitives or blocks rather than product research. [1](https://ui.shadcn.com/docs)

## Side-by-side

| Criterion | Lazyweb | shadcn/ui |
| --- | --- | --- |
| Best for | Use Lazyweb when deciding which onboarding, trial or monetization change to test in your product. [3](https://design.lazyweb.com/) | Use shadcn/ui when you need editable UI primitives or blocks rather than product research. [1](https://ui.shadcn.com/docs) |

[6](https://design.lazyweb.com/pricing) | Open-source components; third-party block registries set their own terms. [1](https://ui.shadcn.com/docs) |
| Library depth | 281k+ real app screens across iOS apps and marketing pages. [3](https://design.lazyweb.com/) | A component and block collection, not a corpus of captured commercial apps. [2](https://ui.shadcn.com/blocks) |
| Platform coverage | iOS apps and marketing pages today; web-app flows are not available yet. [3](https://design.lazyweb.com/) | React web interfaces. [1](https://ui.shadcn.com/docs) |
| MCP / API | Agent-first MCP setup across Codex, Claude Code, Cursor, Antigravity, hosted Claude connector paths, and other agentic platforms. [5](https://www.lazyweb.com/mcp-install) | Official documentation and registry tooling support coding-agent workflows. [1](https://ui.shadcn.com/docs) |

## What shadcn/ui does well

- Code lives in your application and can be customized.
- Components provide a consistent implementation foundation.

## Where shadcn/ui is limited

- You still need to decide what product behavior to build.
- A component’s availability does not establish conversion or retention performance.

## Where Lazyweb shines

- Free human browsing makes it easy to inspect references before choosing MCP access.
- Agent workflows can pull references, app trees, and structured design context instead of relying on generic taste.
- Screen-version history lets agents see how a real product's UI evolved over time, not just one snapshot.

## Where Lazyweb is limited

- Lazyweb does not yet have web-app flows; flows are mobile-first today.
- Human-facing advanced filters are thinner than some paid human-first libraries.
- The product is intentionally agentic-first, so purely manual browsing may feel less polished than specialist galleries.
