About Straply

Straply tracks every residential property in the United States — 140 million homes, updated daily. We collect sale prices, construction dates, tax records, rental data, listing history, and dozens of other data points for every property.

Most real estate data is locked behind expensive enterprise contracts, stale by the time you get it, or limited to a single metro area. Straply is different. We built an infrastructure that continuously monitors the entire U.S. housing market and makes the data available through a simple REST API — starting at $0.

What you can do with it

Developers build PropTech apps, portfolio tools, and market dashboards using our API. One endpoint, any ZIP code, instant JSON.

Investors find rental yield hotspots, track flip activity, and monitor foreclosure waves across every metro in the country.

Real estate professionals get neighborhood-level market intelligence that used to require six-figure data subscriptions.

The data behind the visualizations

Our interactive heatmaps let you watch decades of housing history unfold — from the post-war suburban boom to the 2008 foreclosure crisis to the post-COVID price surge. Every hex on the map represents real transaction data, not estimates.
