Items submitted to the workshop aren't immediately usable in Rust. Instead, the developers are looking to the community to put forward their creations for consideration to be included in the game. These items may (in the future) be available to purchase from the Rust item store.

Facepunch rotates the Rust item store roughly once a week, adding a small set of skins for a limited time. SCMM records every rotation, so you can browse the current one, see how long is left before it changes, and go back through past rotations to see what was on sale and what it sold for.

Market cap is an item’s price multiplied by how many copies exist, and the Rust Market Cap is that total across every skin listed on all tracked marketplaces — one number for the size of the entire Rust skin economy. The trending table ranks individual skins by that same measure, so you can see which items carry the most value rather than just the highest price.

A Rust Index Fund tracks the average price performance of one category of Rust skins over time as a single value, similar to how a stock market index tracks a basket of shares. Instead of checking every weapon skin individually, the Weapons Index gives you one number that reflects how that whole category is moving. Supply is held fixed across comparisons, so an index moves when prices move — not when our estimate of how many copies exist changes.

Sign in with Steam and SCMM values every skin in your inventory against current market prices, so you can see what the whole thing is worth, which items carry most of that value, and how it has moved over time. Your inventory has to be public for Steam to let us read it.

Item prices, orders and activity are synced with Steam about once every 2 hours on average, and third-party marketplaces on their own schedules. Due to Steam request throttling and occasional API down-time, data can lag behind even further than this. Because Steam is a live, high-volume marketplace, real-time updates in SCMM are not feasible.

Not every skin is tradable. Items that were never sold on the Steam Community Market — store-only or non-marketable items — have no market price to show, so SCMM falls back to the store price where it has one and shows a dash where it does not.

Any feedback is appreciated and bug reports are welcomed. Drop a message in the SCMM Discord for help, or submit an issue to the SCMM GitHub issues page.

The development environment isn’t well suited for public contributions and there isn’t time to commit to better workflows, so no help is actively being sought right now. You are welcome to contribute, fork or review the source code on GitHub.

No. SCMM is fan made and not affiliated with Valve Corporation or Facepunch Studios. It aggregates and analyses public data collected from Steam and other sources. SCMM is still under development and may change (or be removed) without notice, and no claim is made that the information provided is accurate — use it at your own risk.

A subset of SCMM data is available through the public API for non-commercial use. Keep request volumes reasonable — excessive spam or abuse can lead to access being revoked. See the Terms of Service for the full wording.
