RandDeck

Draw numbers, pick from a list you type in, or roll dice. It runs on Windows 11 x64 and works fully offline — no account, no internet, no auto-update.

Chinese name: 掷数台. 中文说明：README.zh-CN.md.

What it can do

• Draw from a number range, a custom list, or a dice expression such as 2d6+3
• Skip one number, a range, odds, or evens; optionally take a number out of the pool after it is drawn
• Numbers are generated on this computer. The animation is only for watching.
• Reroll just the results you select, pin a result so the next draw keeps it, add a number to the skip list, or undo the last draw
• Each mode remembers how many numbers you last asked for
• Space or Enter draws immediately; Shift+Space starts a countdown first
• History, plus frequency, coverage, trend, and probability views
• Export JSON, CSV, or PNG; make a full backup in Settings
• Dark, light, and high-contrast themes; reduced-motion is supported
• Switch the whole UI between Chinese and English in Settings
• No accounts, no telemetry, no auto-update, no cloud. Data stays on this computer.

Downloads

Get it from GitHub Releases:

• RandDeck.exe: one file. Microsoft Edge WebView2 Runtime must already be installed.
• RandDeck-v0.6.0-portable.zip: unzip and run. Includes docs, license, a manifest, and SHA256 checksums.
• RandDeck-v0.6.0-offline-setup.exe: installer. Can install WebView2 if the PC does not have it.

This release is not code-signed. Windows SmartScreen may warn about an unknown publisher. Check the published SHA256 before you run a file.

You need Node.js 24 LTS, npm 11, stable Rust, Microsoft C++ Build Tools, and WebView2 Runtime.

Local data and compatibility

• Tauri state: %APPDATA%\com.zhishutai.desktop\state-v5.json
• Browser debugging state: IndexedDB database zhishutai-v5
• Backup format: zhishutai.backup.v5
• Receipt and release schema identifiers still use the zhishutai.* namespace.

Those paths and IDs are left as they were so a v0.5.0 install can upgrade without losing data. They are old internal names, not the public product name. Nothing here is uploaded. Export a full backup in Settings before you move or uninstall the app.
