RoLens

RoLens places live Rolimon's and RoUtility data inside Roblox itself. Values, RAP, demand and USD estimates appear on trades, item pages and inventories, exactly where decisions are made.

Values in place

Every item in a trade carries its value and a USD estimate, with offer totals and the difference between both sides.

Trade previews

The Trades list shows what each offer is worth before it is opened, and flags items that have no value yet.

Read-only by design

RoLens only reads. It never sends, accepts or declines a trade, and every request it makes is documented.

Principles

dyrt is the studio of Simon, a developer building browser software for the Roblox trading community. Three rules apply to everything it ships.

  • Open by default

    All source code is public under the MIT licence, so anyone can read exactly what a tool does before installing it.

  • No hidden access

    No analytics, no remote code, and no requests beyond what each feature documents. This site follows the same rule.

  • Quiet interfaces

    Information appears in place, sized to the page it sits on, and never covers what it describes.
