About

Guppy helps real fans win scarce drops.

It watches Walmart + Pokémon Center for queues, restocks, and “action-needed” moments - then alerts you at the exact time you need to step in (captcha prompts, getting through the queue, inventory going live).

No doomscrolling Discord. No staring at a queue for hours. Just focus on the moments that matter.

WHAT GUPPY DOES

- Queue monitoring (Walmart + Pokémon Center)
Get notified when a queue starts, when you’re through, or when something changes.

- Action-needed alerts
Captcha detected? Queue exit? Guppy pings you to return to the tab now.

- Restock alerts
Fast notifications when inventory flips.

Swarm signals
Community confirmations that reduce noise and false alarms.

HOW IT WORKS

- Turn on monitoring for Walmart + Pokémon Center

- Keep browsing/working normally

- Guppy alerts you when it’s time to act

ALSO INCLUDED

Market price overlays on eBay (raw / PSA 9 / PSA 10 benchmarks)
