CLUSTER ACROSS-PRICES-WEB · 96 ENTRIES · EARLIEST ENTRY 2025-01-22
E-commerce price tracking alerts
This cluster consists of web apps and platforms that monitor product prices across online retailers and notify users when prices drop or hit target levels, typically via email, Telegram, or push alerts. The dated history is sparse and long, starting with a single 2015 entry, then a gap until late 2024, followed by a slow trickle through 2025 and a slightly higher count in early 2026. The leading products by activity signal are Tiendly, monitoramento-precos-supermercado, and dealdrop, all with 0 stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
