Guppy: Collector Copilot

Guppy automatically tracks restocks, demand shifts, and real market prices across eBay, Pokémon, and major TCG sites, transforming how you shop for collectibles. Stop relying on slow Discord pings and social media noise. Guppy helps you shop smarter across eBay, retail drops, and Pokémon Center by detecting restocks and demand spikes faster than social platforms and surfacing real market prices. With Guppy, you always know when something big is about to happen. HOW IT WORKS Guppy uses a Safari web extension (included with this app) plus this companion app. 1) Enable the Guppy Safari extension (you’ll be prompted in the app). 2) Browse as normal on eBay, Pokémon Center, and other collectible sites in Safari. 3) Guppy aggregates anonymized signals from the Guppy network and sends real-time alerts to this app for drops, queues, restocks, and price moves. With the Safari extension, Guppy can also overlay accurate raw, PSA 9, and PSA 10 benchmarks directly onto eBay card listings in your browser. The mobile app acts as your hub for notifications and configuration on the go.
