Fastest Delivery

Prioritizes offers with Prime, store pickup, or the shortest estimated delivery window.

Price Comparison

Real-time price sync — Prices refresh multiple times daily across all tracked retailers.

Why not scraping?

Scraping works for demos. It breaks in production — sites change layouts, add captchas, block IPs, and require constant maintenance. BuyWhere replaces fragile scrapers with direct data partnerships that stay reliable as your agent scales.

Dimension	Scraping	BuyWhere
Data structure	HTML parsing, fragile DOM dependencies	Normalized JSON, consistent schema
Maintenance	High — site changes break scrapers	Low — partner APIs are stable
Reliability	Unpredictable — blocks, captchas, rate limits	99.9% uptime SLA, no blocks
Freshness	Best-effort, often stale	Multiple daily refreshes, sub-24h window
Scalability	Breaks under scale, requires proxies	Built for agent-scale query volumes
Latency	Variable — 500ms to 5s+	Predictable — P50 120ms, P95 210ms
Legal risk	Terms violations, potential legal exposure	Licensed data partnerships, compliant
Agent integration	Requires custom parsing logic per site	Tools-ready MCP interface, drop-in

BuyWhere maintains data partnerships so your agents never have to debug a broken scraper.
