📥 Download & Installation

🎯 Download opencode-portable Now

Step-by-Step Download

Visit this link to download the application.
Click the download button on the page (it's the latest release).
Save the downloaded file to a folder of your choice (a USB drive or your Desktop works great).
No installation needed—you're ready to go!

▶️ How to Run It

First Time Use

Double-click the downloaded file (it's called opencode-portable.exe or similar).
A small window will appear asking you to pick a folder.
Choose any folder where you want to work (e.g., a project folder, your Documents, or a folder on your USB).
Click OK or Select Folder—and you're in!

Using opencode

A terminal window will open with opencode ready to assist you.
Type your coding question or task (e.g., "create a Python script to sort files" or "explain this error").
The AI will respond right there with code, explanations, and suggestions.
You're working offline—no internet connection needed after download.

🛑 How to Quit & Keep Zero Traces

When you're done, closing opencode is simple—and crucially, it leaves absolutely nothing behind on the host computer:

Quick exit: Close the terminal window by clicking the X button in the top-right corner.
Keyboard shortcut: Press Ctrl+C (or Ctrl+Break) while the terminal is focused.
Force quit: If needed, press Ctrl+Shift+Esc to open Task Manager, find opencode-portable, select it, and click End Task.

After quitting, opencode-portable automatically cleans up:

No temporary files left in AppData
No registry entries
No history or cache
No background processes

Your work stays in the folder you chose; everything else is wiped on exit.

🔒 Privacy & Portability

Zero-Trace Guarantee

This launcher is built with privacy at its core. Unlike typical apps that scatter files across your system, opencode-portable:

Runs 100% from its own folder (or a temp folder that self-deletes)
Writes nothing to your system drive outside its own directory
Clears all caches and logs on exit
Leaves no startup entries or services

USB Portable Use

Take it anywhere:

Copy the single .exe file to any USB stick (FAT32, exFAT, NTFS—all work).
Plug it into any Windows 10/11 machine.
Double-click and start working.
When done, quit—the USB is clean and ready for the next machine.

🎯 What Can You Do With It?

opencode is your AI pair programmer. Here are common use cases:

Fix bugs: Paste an error, get a fix.
Write code: Ask for a script, function, or full module.
Learn: Ask "what does this code do?" and get a clear explanation.
Review: Ask for best practices or performance improvements.
Refactor: Request cleaner, more efficient implementations.

It works with all major languages: Python, JavaScript, C#, Java, Go, Rust, and more.

🛠️ Included Scripts & Tools

The download includes:

The main launcher (opencode-portable.exe) – the full offline runtime
Helper scripts (optional) for advanced users:
- start.ps1 – PowerShell script to launch with custom settings
- clean.ps1 – Manual cleanup if you ever need it (rarely needed)

You can ignore these if you're a first-time user—just use the main .exe.

❓ Troubleshooting

"Windows protected your PC" (SmartScreen warning)

This is normal for portable software. Click More info → Run anyway. It's safe (MIT-licensed, open-source).

Antivirus false positive

Some antivirus tools flag portable apps. Add the .exe to your AV exclusions or run it from a thumb drive (most AVs skip USB). The source code is public on GitHub—no malware, ever.

The folder picker doesn't appear

Make sure you're running the .exe directly (not opening it inside an archive). Extract it first if you downloaded a .zip version—but normally it's a single .exe.

Terminal doesn't open

Try running it from a folder with write permissions (e.g., Desktop). Avoid system folders like C:\Windows.
