Uninstall

Nexora Lab provides multiple uninstallation methods with intelligent data cleanup options.

Using CLI Command (Recommended)

The simplest way — works cross-platform without downloading scripts:

nexora uninstall

This will:

1. ✓ Find your installation automatically
2. ✓ Ask if you want to keep or delete your data
3. ✓ Remove the binary and optionally your configuration/history
4. ✓ Clean up Windows PATH registry (Windows only)

Using Standalone Scripts

Linux / macOS

curl -fsSL https://lab.getnexora.cloud/uninstall.sh | bash

Windows (PowerShell)

powershell -c "irm https://lab.getnexora.cloud/uninstall.ps1 | iex"

npm Uninstall

If you installed via npm:

npm uninstall -g nexora-lab

Note: npm uninstall removes the binary only. Configuration and conversation history are preserved at ~/.config/nexora-lab and ~/NexoraLab.

Manual Uninstall

Linux / macOS

# Remove binary
rm /usr/local/bin/nexora
# or if installed to ~/.local/bin:
rm ~/.local/bin/nexora

# Optional: Remove all data
rm -rf ~/.config/nexora-lab        # Configuration & API key
rm -rf ~/NexoraLab                 # Database & conversation history

Windows (PowerShell as Administrator)

# Remove binary
Remove-Item "$env:LOCALAPPDATA\NexoraLab\bin\nexora.exe" -Force

# Remove from PATH (PowerShell as Admin)
$UserPath = [Environment]::GetEnvironmentVariable("Path", "User")
$NewPath = ($UserPath -split ';' | Where-Object { $_ -ne "$env:LOCALAPPDATA\NexoraLab\bin" }) -join ';'
[Environment]::SetEnvironmentVariable("Path", $NewPath, "User")

# Optional: Remove all data
Remove-Item "$env:APPDATA\nexora-lab" -Recurse -Force           # Configuration & API key
Remove-Item "$env:LOCALAPPDATA\NexoraLab" -Recurse -Force       # Database & conversation history

Data Preservation

By default, the uninstall wizard keeps your data:

• ✓ API key is preserved
• ✓ Conversation history remains
• ✓ Model preferences saved
• ✓ You can reinstall and continue where you left off

Choose "Yes" during uninstall to delete everything for a clean removal.

Requirements

• A free OpenRouter API key — Nexora Lab will prompt you on first launch.
• No Node.js needed when using the binary installer. The binary is fully self-contained.

Releasing a new version

git add .
git commit -m "feat: your changes"
git tag v1.1.0
git push && git push --tags

GitHub Actions will automatically:

1. Bundle the code with esbuild
2. Build self-contained binaries for all 5 platforms
3. Publish a GitHub Release with all binaries attached
4. The install scripts always pull /releases/latest/download/ so users get the new version automatically

Setting up the Vercel distribution site

1. Create a new Vercel project and import vercel-site/ as the root
2. In Vercel project settings → Domains → add lab.getnexora.cloud
3. In your DNS (wherever getnexora.cloud is managed), add a CNAME:

   lab  →  cname.vercel-dns.com

4. Deploy. The scripts are now live at:
   • https://lab.getnexora.cloud/install.sh
   • https://lab.getnexora.cloud/install.ps1

When you update the installer scripts, copy them to vercel-site/public/ and push — Vercel redeploys in ~10 seconds.

Config storage

| OS | Path | |---------|-----------------------------------------------| | Linux | ~/.config/nexora-lab/config.json | | macOS | ~/Library/Preferences/nexora-lab/ | | Windows | %APPDATA%\nexora-lab\config.json |
