The page was updated **September 2026**. Transitions.dev provides interactive web-transition examples usable through an agent skill; use it when implementing a particular interface transition. [Source 1](https://transitions.dev/) ## Choose Lazyweb when You need 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.

[Source 1](https://transitions.dev/) ## Comparison | Criterion | Lazyweb | Transitions.dev | |---|---|---| | Best for | Researching real product patterns before designing with an AI agent. [Source 2](https://www.lazyweb.com/) | Implementing a particular interface transition. [Source 1](https://transitions.dev/) | | Pricing | Human browsing and MCP setup are free. Pro is **$39/month** for the complete toolkit except competitive tracking. Team is **$99/month** for up to five seats and competitive tracking.
