v1.0.4

Run the same Windows app many times, each with its own profile. This release makes many more apps work as real separate copies and makes Save reliable.

Download

  1. Download MultiBox-v1.0.4-win-x64.zip below.
  2. Extract it anywhere and run MultiBox.exe. Nothing is installed; no admin rights needed.
  3. Windows may show a SmartScreen warning the first time: click More info → Run anyway. Releases are signed with a self-signed certificate (CN=zer0ne), which Windows doesn't recognize as a known publisher.

Verify the download (PowerShell):

Get-FileHash .\MultiBox-v1.0.4-win-x64.zip -Algorithm SHA256

Expected SHA-256: C66C52C9CDC4F4C08EEA1ECEB84ADA97E92470547EC9F5275D5232BF8C1E5EA2

What's new

Added

  • App compatibility layer for apps that collide through things a profile folder can't separate:
    • OpenCode Desktop and Cline get their own background-service ports per session, fixing "Managed service port 45278 is already in use" and copies sharing Cline's hub.
    • Tauri apps (such as Cline) open as a real second copy instead of handing off to the open window.
    • WebView2 apps that keep data next to their .exe get their own data folder per session.
  • Saved profiles in Vault → Saved now show when they were saved and how large they are.
  • New sharp, vector-based app icon with dedicated small sizes and sizes for 125% / 150% display scaling.

Fixed

  • Starting an app normally from Windows could open the isolated copy instead (Tauri apps). Normal and isolated copies no longer capture each other's launches, in either order.
  • Save reported "The app is still open" for Cline and Codex. Save now closes every real window and repeats the request if the app opens a new one while closing.
  • Save could fail on the first try with "Could not capture '…sqlite'" when a database was briefly held. Database copies now retry short-lived holds safely.
  • Saved profiles no longer include browser caches of apps with their own data folder, or OpenCode's 200 MB bundled CLI.
  • Opening About could shift the whole window sideways.
  • Microsoft Store desktop apps (Codex, Claude) start in a session again.
  • Reopening saved Chromium/Electron profiles no longer shows a "Profile error" dialog.

Changed

  • Delete sessions & saved profiles… moved into Settings → More options.
  • README, architecture guide and website rewritten with a step-by-step guide, compatibility table and FAQ.

Good to know

MultiBox separates app profiles (logins, cookies, settings). It is not a security sandbox: the registry and Windows Credential Manager are shared between copies. See What is not separated.
