How the UIQ score works

Frequently asked

How are these dev tools ideas scored?

Against the same eight-signal UIQ rubric as every idea in the catalog. Demand and feasibility carry the most weight, and anything under 55 is cut at the gate, so what is here has cleared the bar.

Can I build one of these solo?

That is what the codeability and feasibility sub-scores measure, shown on every idea. Most are a real two-week build for one person working with a coding agent.

Can I see one in full before paying?

Yes. The Idea of the Week is unlocked completely, free, with no account, so you can read a full plan and kit before deciding.

Will someone else build the same idea?

Possibly, and that is fine. Execution and distribution decide these markets, which is why every idea here ships with a full launch kit rather than with just a spec.

Why are some rated CAUTION?

Because the opportunity is real but carries a named risk, and burying that would make the whole catalog worth less. A CAUTION is worth building with your eyes open, and the risk is written on the page.

How often does this page change?

Whenever an idea in dev tools clears the bar and publishes. The page is built from the same index as the catalog, so it can never list an idea that is not really there.
