Caskit

Caskit is a free, open-source desktop app for Counter-Strike 2 inventories. It moves items into and out of storage units in bulk with self-tuning speed and transfer rules, shows every trade-up outcome with its chance and expected float, applies, scrapes and removes stickers, and includes the CS2 store with a cart, trades, the Steam Community Market and Steam Guard confirmations. Several accounts can be signed in at once, each with its own proxy, via QR code, password or maFile. It runs entirely on your computer and talks only to Steam — no servers, subscriptions or telemetry. Available in 10 languages for Windows, macOS and Linux.
