No. CS2Lab is an independent fan-made tool. Prices come from Steam Market, Skinport, and Waxpeer. Not affiliated with Valve Corporation.
Yes. CS2Lab is fully responsive and works on phones and tablets.
Yes. Valve's official figures published via Perfect World (Sept 2017): 79.92% Mil-Spec · 15.98% Restricted · 3.2% Classified · 0.64% Covert · 0.26% knife/gloves. These haven't changed since CS:GO.
Using CS2's actual float formula — a random seed is mapped through the skin's min/max float range, then renormalized to only the wear bands that skin is actually available in.
450+ containers — weapon cases, sticker capsules, souvenir packages, autograph capsules, music kit boxes, and Terminal collections.
StatTrak is applied at a community-verified 10% rate per eligible skin drop. Knives and gloves cannot be StatTrak.
Every CS2 weapon case ranked by expected value (EV) — the average dollar return per open. Calculated using official drop rates, float-weighted wear probabilities, and per-phase Doppler pricing.
Steam charges a 15% marketplace fee when you sell items. Net mode deducts this from EV and ROI so you see what you'd actually pocket, not just the gross sale price.
Prices refresh every 5 minutes from Steam Market floor prices.
A (≥−25% ROI) · B (≥−40%) · C (≥−55%) · D (≥−70%) · F (<−70%). No case has positive ROI — the grades reflect how much less bad one case is vs another.
Set a budget and pick a color vibe (All White, Fade, Gold, Red, Blue, Purple and more). Claude AI picks the most cohesive skin set across 17+ weapons using real-time prices from Steam Market, Skinport, and Waxpeer.
Yes. Lock any skin you already own or love — the AI keeps it and regenerates only the unlocked slots.

Yes — you can add any knife type and glove type to your loadout. The AI will pick a matching skin within your budget.
Combine 10 CS2 skins of the same rarity to receive 1 skin of the next rarity tier. CS2Lab simulates all possible outputs, calculates the output float using CS2's actual formula, and shows your expected P&L.
The float math uses the real CS2 formula. Output skin probabilities are weighted by collection distribution. However this is a simulation — do not use it to make real financial decisions.
Industrial Grade → Mil-Spec → Restricted → Classified → Covert. Covert trade-ups require only 5 skins and can output knives/gloves.
