Inspect Lazyweb examples
What 21st.dev does well
- Preview components and copy source into your repository.
- Multiple authors and styles in one catalog.
Where 21st.dev is limited
- Authored components are not evidence of how a production app performed.
- Check membership, template licenses and AI credits separately.
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.
