Why Lazyweb is different

Lazyweb is not trying to be just another gallery. It is built so agents can do competitive analysis, inspect references, read app-tree context, and use mobile A/B test evidence when deciding what to build.

The honest limitation: Lazyweb does not yet have web-app flows, and the UI is less advanced for humans who only want manual filtering.
