About PropHerald

map · data status · feedback

PropHerald is a knowledge base for Singapore property. It brings the public data that actually matters when judging a home — prices, transit, shelter, schools-to-come, health and environment — onto one map, refreshed automatically every day.

What's inside

• Every private residential transaction of the last five years (URA) and every HDB resale since 1990 — about 1.1 million transactions
• All 164,288 building footprints in Singapore, clickable for per-building price history and surroundings
• Active dengue clusters (NEA), refreshed daily
• Bus stops and covered linkways (LTA) — how sheltered is the walk?

Sources are polled on schedules from hourly to monthly and archived immutably; the data status page shows the live health of every feed.
