A serious CS2 trader’s browser ends up with the same dozen tabs open most days. These are them — the apps that earn a permanent bookmark slot for case math, portfolio tracking, pattern hunting, price discovery, and getting an item out of your inventory at the best price. Twelve picks, ranked by how often you’ll actually reach for them.
How we chose
Each entry has been hand-tested against a real CS2 inventory in the last 90 days against our five-criterion rubric — accuracy, breadth, UX, freshness, and pricing transparency. No paid placement, no affiliate prioritisation. Tools that duplicate something already on the list dropped off; we only included one tool per job-to-be-done unless two are genuinely differentiated.
The twelve, ranked by daily utility
#1 — CSROI · Case ROI
Live ROI for every CS2 case, plus an Armory ROI view and an arbitrage scanner.
#2 — CSStonks · Case supply
Long historical supply charts — knows what cases are getting rarer in real time.
#3 — Pricempire · Price aggregator
Aggregates 7+ marketplaces and ships a free API — the canonical data layer of the niche.
#4 — CSGOSkins.gg · Price aggregator
29+ marketplaces in one search; shop for the cheapest listing anywhere.
#5 — cs2.sh · Historical charts
OHLC candlestick charts for individual skins — the stock-chart view of the market.
#6 — SteamLedger · Portfolio tracker
Steam-OpenID auto-sync, 15-minute refresh. The default tracker for most traders.
#7 — SkinFolio · Portfolio tracker
Indie alternative with an explicit "always free" commitment — no premium tier on the roadmap.
#8 — CSBlueGem · Pattern database
The canonical database for Case Hardened blue gems and tier rankings.
#9 — Dispattern · Pattern database
Doppler phases, Marble Fade FFI, Crimson Web tiers — broader pattern coverage.
#10 — CSFloat · Marketplace

#11 — Skinport · Marketplace
EU-focused marketplace with weekly native SEPA payouts.
#12 — CS2 Sticker Tracker · Sticker tools
Applied-sticker premium pricing and capsule ROI — purpose-built for sticker traders.
Workflow: how a typical trade actually uses these
A real day-in-the-life for a serious trader looks something like this. Open Pricempire to check what’s moved overnight; if something interesting, jump to cs2.sh for the historical chart. If you’re considering buying, run it through CSGOSkins.gg to find the lowest current listing across 29 marketplaces. Buy on CSFloat if it’s English-speaking and you want the lowest fees, or Skinport if you’re in the EU and want SEPA payout. Track the position in SteamLedger alongside the rest of your inventory. When you’re ready to sell, re-run the same loop in reverse.
What we left off the list
Plenty of CS2 tools exist that don’t earn a daily slot. They cluster into three buckets: (1) duplicate categories where one tool already wins (we don’t need three portfolio trackers), (2) one-trick utilities that solve a problem you encounter quarterly — useful but not bookmarked, and (3) sites that haven’t been updated in 12+ months. The full directory has the long tail.
