CartBuddy

CartBuddy watches price and availability from your own logged-in browser, then prepares checkout when the rules you set finally match.
In stock and within your price limit.
Watching locally. Next check has been scheduled.
Not another cloud scraper.
CartBuddy works where your retailer session already lives. The server manages your subscription and devices—not retailer scraping.
Add a Walmart product URL and CartBuddy identifies the product, current offer, and seller.
Choose the maximum item price, quantity, check interval, and fulfillment preferences.
Checks happen locally through your own authenticated browser session with sensible pacing.
When price and stock match, CartBuddy revalidates the cart and prepares a guarded checkout.
CartBuddy doesn’t ask for your Walmart password, payment card, CVV, or retailer session cookies. It works with the address and payment method you already saved with the retailer.
Read the privacy summaryProduct checks and checkout interactions execute in your browser, not from a scraping farm.
Payment credentials remain with the retailer. CartBuddy does not collect or store them.
Price, stock, product identity, quantity, and seller details are checked again before checkout.
Pause or delete watches at any time. Automatic order submission is not enabled in the alpha.
We’re validating the complete local monitoring and checkout flow with Walmart before adding more retailer adapters.
CartBuddy is in active development. Early testers get direct access to the team and a voice in retailer support, safeguards, and launch pricing.
Requesting an invitation is free. Any paid checkout will show pricing and renewal terms before billing begins.
