SkinFast is a real-time CS2 skin pricing and tradeup optimization tool. It scrapes the entire Steam Community Market, 21,000+ items, into a local SQLite cache, then runs an optimizer that finds the most cost-effective tradeup contract for any target skin. Under the hood it solves three problems: ingesting market data without getting rate-limited, modeling tradeup probability across multi-collection input pools, and ranking input combinations by cost-per-attempt and expected value.

01 — Web Scraper
Full Steam Market scraper with 21,000+ live items
A custom scraper crawls Steam's entire Community Market, 21,000+ items, with jittered delays, exponential backoff, and resumable offsets. A full pass completes in about 15 minutes without triggering rate limits.
02 — Real-Time Prices
Live pricing via stale-while-revalidate caching
Bulk scrapes every 4–6 hours hydrate a local SQLite cache, and on-demand refreshes keep high-traffic items current. Cached prices serve instantly while background jobs pull the latest data from Steam.
03 — Tradeup Algorithm
Probability modeling and cost-per-attempt ranking
For any target skin the optimizer enumerates input combinations across collections, models per-skin probability, and ranks candidates by cost-per-attempt and expected value, surfacing positive-EV contracts automatically.
04 — One of a Kind
The only site in the world with the most profitable tradeups
No other platform combines a full live-priced catalog with a probabilistic optimizer. SkinFast surfaces tradeup contracts that don't appear anywhere else, giving users an edge that simply isn't available on any competing tool.
