RoTrail is a browser extension for following changes to selected public Roblox profiles and limited items. It keeps an activity trail so users can review changes over time rather than repeatedly checking the same public pages. Profile history and limited-item metrics are distinct parts of the product. RoTrail is intended for people who want to keep track of public Roblox activity and item information. It does not provide access to private inventories or promise real-time updates or trading profits.
