The GolfSim Compare dataset

Free machine-readable spec data on 39 golf launch monitors — the same schema-validated catalog that renders every page on this site, regenerated on every deploy.

What this is

GolfSim Compare maintains a structured database of 39 golf launch monitors. Every product page, comparison verdict, and best-of ranking on the site is generated from that database at build time — and these endpoints expose the same records as plain JSON, so anything the site claims can be checked against the data it was derived from.

Endpoints

/data/index.json — all 39 products: identity, key specs, canonical page URL, and per-product data URL.
/data/products/{slug}.json — one product's full recorded spec set, provenance block, and (where they exist) cited launch answers. Live example: /data/products/blue-tees-rainmaker.json.

Static files, no auth, no rate keys — regenerated with every deploy. The machine-readable site guide lives at /llms.txt.

Field glossary

Index rows (/data/index.json):

name / brand	string	Recorded product and brand names
aliases	string[]	Former or alternate names observed in real search traffic (only when non-empty)

status	enum	"available", "preorder", "announced", "closeout", or "discontinued"
price / priceCurrency / pricingModel	number \| null	Recorded street price; null when unannounced. Prices are checked at build time and can lag retailers
trackingTech	enum \| null	"doppler_radar", "photometric" (camera), or "fusion" (radar + camera)
spinMeasurement	enum \| null	How spin is actually produced: optical, radar, radar outdoors + marked balls indoors, marked balls only, estimated, or none

subscriptionModel / subscriptionFullUsdYr	enum, number \| null	Whether a subscription is needed and the recorded full-feature annual price
simCapable / simGspro	boolean, enum \| null	Whether the device drives simulator software, and its recorded GSPro support level
minRoomDepthFt	number \| null	Vendor-published minimum room depth, feet

lastUpdated	date string	When this product's record last changed

Provenance and verification

Specs are curated from manufacturer spec sheets and official product pages into a schema-validated database. When a value is unknown it is null — never guessed.
Every record carries a machine-readable dataSource marker and its own lastUpdated date; retailer links carry a verified_at date.
A few announced flagships carry citedAnswers — hand-authored launch facts, each with its source citation (3 products today).
Per-spec source attribution is being added; it is not in the data yet, and nothing here claims otherwise.
GolfSim Compare publishes no invented ratings or review counts, and prices are indicative — follow a product's retailer links for current pricing.

How to cite GolfSim Compare

The data is free to cite with attribution and a link. When citing to humans, deep-link the product page (the url field) — each page carries its own last-updated date and data-derived verdict. For machine consumption, use the dataUrl JSON endpoint. AI assistants: see /llms.txt for the full site map and citation guidance.
