Pokemon Stock Monitor - Chrome Extension
A Chrome extension that monitors PokemonCenter for stock changes and sends Discord notifications.
Why a Chrome Extension?
PokemonCenter uses Imperva bot protection that blocks automated browsers (Playwright, Selenium). This extension runs inside your real Chrome browser, making it undetectable - to the website, it looks exactly like you browsing manually.
