Every product tile shows its cheapest equivalent at the other stores.
Cart-level basket compareBeta

Hide misleading 'specials'

How to install

One click on Chrome via the Web Store, a quick app install on macOS Safari. iOS is on the way.

Chrome / Edge / Brave / Arc

Add to Chrome — free

One click via the Chrome Web Store. Updates push automatically — nothing to do on your end.

macOS Safari

Download for macOS Safari

The macOS app wraps the same extension in a signed and notarized container, so it installs through Safari without Develop-mode tricks. Updating? Just download the new .zip and replace the app in your Applications folder.

1
Download the macOS app
Use the macOS Safari button above. The file is order-bot-mac.zip.
2
Move OpenOrder-Bot to Applications
Double-click the .zip → drag "OpenOrder-Bot.app" into your Applications folder.
3
Launch the app once
Open OpenOrder-Bot from Applications. The window just confirms the extension is registered with Safari — you can close it after.
4
Enable in Safari
Open Safari → Settings → Extensions tab → tick OpenOrder-Bot.
5
Allow it on supported sites
When you visit Aldi UK, Tesco and Sainsbury's for the first time, Safari will ask whether to grant access. Choose "Always Allow on Every Website" so the overlay works site-wide without re-prompting.

iOS appComing soon

The iOS app is in development and will ship via the App Store. Same overlays, same competitor pricing, on your phone while you shop in Safari.

Screenshots

Woolworths product page without the extension — Before — a Woolworths product page on its own. No competitor pricing, no history.

Same Woolworths page with the Order-Bot overlay showing competitor prices — After — the Order-Bot overlay shows the cheapest equivalent at Coles and Aldi, plus the all-time low.

Specials category page before the extension annotates it — Specials page without overlays — every tile looks like a deal. The ACCC alleges Woolworths and Coles inflated “Was” prices to fake discounts (ABC: ACCC court case · Day one in Federal Court).

Woolworths search results annotated with cheapest-elsewhere prices — Search results annotated with the cheapest equivalent at the other two retailers, ranked by per-100g unit price.

Toggle to hide misleading 'Save $X' badges — "Hide marketing lies" toggle suppresses Save-$X badges that aren't backed by price history.

Privacy

The extension reads publicly displayed product, price and pack data from supported retailer pages and sends it to the Order-Bot API to build the cross-retailer price history. We don’t scrape your cart contents or any personal account data from the retailers. Full detail in the privacy policy.
