Rotility is a free value guide and market tracker for Roblox limiteds. It started in 2026 with one question that kept coming up in every trade: what is this item actually worth, right now? Not what a list says it was worth last month, and not what a few self-bought sales pushed its RAP to.
Trading limiteds runs on values, and for years those values came from a few sites where a small group decided the numbers. They were slow to move, easy to argue with, and blind to most of what actually changed hands. Roblox’s own RAP was no better: a handful of self-buys could make an item look worth twice its real price.
Rotility takes a different route. Instead of asking people what things are worth, it watches what they do: every sale on the Roblox market and every trade between the players it follows. A valuation AI built for this market reads that evidence the way an experienced trader would, and Rotility publishes the result with the receipts attached.
It grew from there: live deals, a trade tracker, player histories going back years, a market census of who owns every copy, values in US dollars that always follow the Robux value, and Protility for the people who trade every day.
Every listing and every sale of every Roblox-made limited, around the clock. The cheapest copies are checked every few seconds.
Rotility rescans thousands of trading inventories and compares them, so it sees trades as they happen, not just what sold on Roblox.
Fair trades, real sales, community polls and value proofs go into one picture. Projected RAP and staged sales are thrown out, and unbalanced trades count for less.
Confidence bars say how much stands behind a value, adjusted values carry a note saying why, and thin markets are flagged instead of hidden.
