Discount Bandit is a free, open-source, self-hosted price tracker for Amazon, eBay, and more, with a browser extension and Telegram/Ntfy price alerts.
Discount Bandit is a free, open-source, self-hosted price tracker built for people who want to monitor product prices without depending on a commercial browser extension or SaaS service. Maintained by a developer known as Cybrarist and distributed via GitHub, Docker Hub, and the Chrome Web Store, it pairs a self-hosted dashboard with a browser extension for adding products directly from a store's product page.
The project explicitly avoids collecting user data or using analytics, positioning itself as a privacy-first alternative for deal hunters and home-lab enthusiasts who want full control over their shopping-tracking data.
Discount Bandit supports more than 25 built-in retailer integrations, including Amazon, eBay, Walmart, Costco, and AliExpress, plus unlimited custom stores and community-contributed store configurations for retailers not natively supported.
Notifications are delivered through Ntfy, Telegram, or Gotify based on rules users define per product, such as a target price, a percentage discount, the lowest price seen in a time window, stock changes, or seller verification status. The system supports multiple users on a single instance, with admin-configurable link limits per account.
Discount Bandit is completely free and open source, with no paid tiers, subscriptions, or licensing fees. Users self-host the application, typically via Docker, Docker Compose, or Portainer, and bear only their own server hosting costs.
Because there is no managed cloud offering, all functionality — multi-user support, unlimited tracked products, and community store integrations — is included at no cost to anyone willing to run their own instance.
