Hey. I built Lume, a Chrome extension that shows a price history graph on any product page (Rozetka, Amazon, basically any store). You can instantly see if a "sale" is real or if the store just inflated the price before the promo.
It also searches for the same product across other stores and shows where it's cheaper.
Stack: Chrome Extension MV3 + FastAPI + SQLite. There's also a Telegram bot for price drop alerts.
Currently tracking 53k+ price points across 1,100+ stores.
Would love any feedback, especially if something breaks on a store you use. There's a report button both in the extension and the bot.
