context

The Dutch points system (WWS) is public and precise, yet reading a listing into it by hand is slow and easy to get wrong.

WWScore does the reading, and shows its working — every point earned is traced back to the rule that earned it.

approach

A listing is parsed into the scoring rules — surface, energy label, amenities, WOZ value — and each contribution is attributed to its source.

Nothing is asserted that can’t be checked against the regulation behind it.

traced back to the rule that earned it — nothing asserted, all checkable

result

A live calculator: a point total and the maximum lawful rent, with the derivation laid out beside it.

A tenant or a landlord can audit the number rather than take it on faith.
