CSDelta is a free toolkit for Counter-Strike 2 players who want to research skin trade-ups, track item values, and explore the skin market. It brings together tools for planning trade-up contracts with float validation, finding potentially profitable trade-ups through community discoveries, and scanning inventories for trade-up opportunities. Its Terminal and Sniper tools help users explore low-float items, sticker crafts, and deals. Players can also estimate the value of a Steam inventory across markets, compare live skin prices from 27 marketplaces, and explore case odds, return on investment, and simulated openings.

The site also offers giveaways, coins, raffles, community prizes, and a saved area for trade-ups and inventories. Educational resources include guides and articles on trade-up strategies, inventory value, skins, and CS2 bans. CSDelta shares marketplace and affiliate information and invites users and businesses to contact the team with questions or collaboration inquiries. The company states that it is not affiliated with Valve Corporation and provides access to its community through Discord.
