Brick-Tracker is a LEGO® price-comparison and marketplace service that helps fans find deals, track sets and explore the wider LEGO market. Its website compares prices from more than 50 shops across thousands of sets, highlights current offers by theme and updates its database automatically. Shoppers can search for sets, create wishlists and set price alerts to hear when a chosen price is reached. The service also shares live deal notifications through its app and community channels, including Telegram and Discord.

Beyond shopping, Brick-Tracker offers tools for managing a LEGO collection, following set values and reviewing price trends, market developments and retirement (EOL) information. Its marketplace supports buying and selling sets within the community, with both private and commercial offers. The site covers popular themes such as Star Wars, Technic, Harry Potter, City and LEGO Friends, and publishes news, set updates, reviews, buying advice and investment articles. Brick-Tracker describes its price-comparison service as free and says it is funded by commissions on successfully referred sales.
