Coming from Casemove? Casemove now shows a deprecation notice: “Casemove has been replaced by Skinledger… Prices, images and items will break in Casemove eventually” (source). Skinledger is a paid service: its free version only moves items, while fast transfers, store purchases, trade-ups, Armory, more accounts, trades and market tools need a subscription of $9.99–24.99 per month (FAQ, pricing, October 2026). Caskit does all of that for free, with no account on anyone's website — and the code is open.

Features

Storage units

• Move items into and out of storage units in bulk. The speed tunes itself to Steam's limits (usually 8–13 items/s), and stuck items are retried automatically.
• Transfer rules: “all cases → Cases 01, Cases 02…”, “stickers → Stickers”. Run them with one click or right after sign-in.
• Rename units, hide full ones, and export everything to JSON/CSV.

Prices and portfolio

• What your inventory and storage units are worth — Steam 7-day average, Buff163 or Skinport prices, in your currency — with a daily value chart and the biggest gainers and losers.
• Portfolio (P&L): import your Steam Market history, add purchases by hand or from CSV, and see the average buy price, unrealized and realized profit (FIFO).
• Prices come from public price lists downloaded every 12 hours; your inventory is never sent anywhere.

Trade-up contracts

• Build contracts from your inventory and from storage units (items are taken out automatically).
• See every possible outcome with its chance, the float of each input, the predicted float of the result and the expected value against what the inputs cost.
• Items the game won't accept (top grade of their collection) are marked in advance. Souvenirs are supported.
• After crafting: the profit or loss of the contract, a detailed item view, Inspect in game and Community Market.

Stickers

• Apply, scrape and remove stickers — including CS2 free-placement stickers.
• An item view like in the game: float to 10 digits, pattern seed, StatTrak™ counter, name tag and sticker wear; inspect links and a link to the item in your Steam inventory.

CS2 Store and Armory

• Cart, favourites, wallet balance and the balance left after purchase. Every payment is confirmed by you.
• Armory: redeem stars for rewards.
• Item names and icons update by themselves from the game files.

Trades, Market and Steam Guard

• Incoming and outgoing trade offers, accept/decline, auto-accept gifts.
• Market: listings, buy orders with the live order book and a 30-day price chart, searchable history, selling with the fee calculated for you (straight from storage units too). Currencies without cents (UAH, KZT, JPY…) are handled automatically.
• A small SDA built in: Steam Guard codes for every account with a maFile, trade and listing confirmations, proxy health monitoring.

Accounts and privacy

• Several accounts at once, each with its own SOCKS5/HTTP proxy — set and check them in Settings or paste a whole list. Pin and reorder accounts.
• Sign in with a QR code (it shows up instantly), a login and password, or a maFile.
• Streamer mode (Ctrl+Shift+H): logins and nicknames become “Account 1, 2…”, the balance is hidden, Steam Guard codes, trade partners and proxies are blurred — safe for videos and screenshots.
• 10 interface languages. Updates only with your consent — or turned off completely.

Download

Get the latest version on the Releases page.

System	File
Windows	Caskit-Setup-x.y.z.exe	recommended — installs in a few seconds, no admin rights, updates itself
Windows	Caskit-x.y.z-portable.exe	no installation (starts slower, update manually)
macOS	Caskit-x.y.z-arm64.dmg (Apple Silicon) / Caskit-x.y.z-x64.dmg (Intel)
Linux	Caskit-x.y.z-x86_64.AppImage or Caskit-x.y.z-amd64.deb

First launch. The builds are not code-signed yet, so the system may warn you once:

• Windows (“Windows protected your PC”): click More info → Run anyway.
• macOS (“app is damaged” / “can't be checked”): right-click the app → Open, or run xattr -cr "/Applications/Caskit.app" in Terminal.
• Linux AppImage: chmod +x Caskit-*.AppImage, then run it.

VirusTotal: every release is scanned automatically — the results and links are at the bottom of each release page.

Uninstall

• Windows (installer): Settings → Apps → Caskit → Uninstall. Portable: just delete the .exe.
• macOS: drag Caskit from Applications to the Trash.
• Linux: delete the AppImage, or sudo apt remove caskit for the .deb.

Your saved sign-ins and settings stay in the data folder (see FAQ); delete it as well to remove everything.

Security and privacy

• Caskit talks only to Steam (and the CS2 Game Coordinator). Your password is never stored; the refresh token and maFile secrets are kept on your disk encrypted by the OS (Windows DPAPI / macOS Keychain / libsecret on Linux).
• If an account has a proxy, all its traffic goes through it, including web requests, the QR code and the avatar. If the proxy is down, sign-in stops instead of going direct.
• The local API listens on 127.0.0.1 only and requires a random token known only to the app window.
• Item names and icons are refreshed once a day from public mirrors of the game files (GameTracking-CS2, counter-strike-image-tracker) — no account data is sent.
• No analytics, no telemetry. Full list of network connections: Privacy policy.

FAQ

Can I get a VAC ban for this? Caskit doesn't touch the game, its files or its memory, and doesn't launch CS2. It signs in as a Steam client and talks to the CS2 Game Coordinator the same way the game's own inventory does, so VAC isn't involved. It is still an unofficial tool, so use it at your own risk.

Can I play while Caskit is open? If you start CS2 on the same account, Steam keeps only one of the two sessions. Sign out of that account in Caskit first.

Are automatic updates safe? Can an update scam me? Caskit never downloads or installs anything on its own. When a new version is out it asks you first — Update, Skip this version or Not now — and in Settings → General → Updates you can choose Don't check to stop even the check. Updates come only from this repository's Releases: they are built by GitHub Actions from the public code (workflow), scanned on VirusTotal, and the installer verifies each file's SHA-512 before installing. The portable version never updates itself. If you don't want to trust any binary at all — build Caskit yourself (below).

Can I build it myself? Yes — everything is in this repository, see Build from source. The :noupdate scripts make a build with updates removed: it never even asks GitHub for a new version.

Where is my data? Only on your computer: %APPDATA%\Caskit (Windows), ~/Library/Application Support/Caskit (macOS), ~/.config/Caskit (Linux).

Build from source

Requires Node.js 22+ and Git.

git clone https://github.com/pythonMaster2002/cs2-storage-manager
cd cs2-storage-manager
npm ci
npm start                      # run
npm run build:win              # installer + portable → dist/
npm run build:linux            # AppImage + deb
npm run build:mac              # dmg + zip (macOS only)

# the same without updates: no update checks, nothing is downloaded
npm run build:win:noupdate
npm run build:linux:noupdate
npm run build:mac:noupdate

Release: bump version in package.json, then git tag vX.Y.Z && git push --tags. GitHub Actions builds all three systems, publishes them to Releases and scans the .exe files on VirusTotal (secret VT_API_KEY); installed copies offer the update.

Code signing policy

Windows releases are built from this repository by GitHub Actions and are intended to be signed through SignPath. Free code signing provided by SignPath.io, certificate by SignPath Foundation. Status: our first application was not approved yet (the project is new), so releases are currently unsigned. We will reapply.

• Committers and reviewers: @pythonMaster2002
• Approvers: @pythonMaster2002

Every signed release is built by CI from a tagged commit and manually approved before signing. Privacy: see the privacy policy — Caskit has no telemetry and sends data only to the services listed there.
